Few facts about JAVA Language

Awesome facts about Learning Java Language

Here we provide Few facts about Java language. Java, the long-lasting programming language,

still immensely famous and for many good reasons. Such as many programmers swear by the
stability of Java. It is a go-to language for millions of software developers.

Java, the long-lasting programming language, still immensely famous and for many good
reasons. Such as many programmers swear by the stability of Java.

1)Java was called Oak at the beginning

Java's original name was oak. It was ultimately converted to Java by Sun's marketing
department when Sun's lawyers found that it was already a computer company registered
as oak. But there is a legend that Gosling and his Gang of Programmers came out to discuss
the names and named for Java. There seems to be some truth in it because the "0xCafeBabe" magic number in class files was named after the cafe where the java team went to coffee.

2)It was just an accident!

James Gosling was working in Sun Labs around 1992. Gosling and his team were building a
set-top box and started with "cleanup" C ++ and wound up with a new language and runtime.
Thus, Java or oak came into existence.

3) You are paid to learn Java

The average salary of a Java developer is 83,975 USD. Yes, it pays to be a Java developer
and programmers are dubbing it.The average number of Java developers are 9 million in
the world.

4)Second most popular language

Although many people would argue that all the time between Java developers is preferred,
Java is the second most popular programming language after.

5)The Duke

The java mascot, 'The Duke' which was made by the bed. Leap is the same guy who has
worked on blockbuster Hollywood, Shrek. The Duke is celebrated in Oracle. A living,
life-size Duke is a popular feature in every Javanese developer conference. Every year,
Oracle issues a new Duke personality.

6)Most popular user interface

Right now, approx 3 billion mobile phones are working in Java, as well as 125 million
TV sets and each Blu-Ray player. This language is constantly ranked top in the rankings
of software developers as the best choice of programming languages.

7)Final is not final in Java

Final really has 4 various meanings in Java.

final class: the class cannot be continued

final method: the method cannot be ignore

final field: the field is a remain same

final variable: the importance of the variable can’t be changed once assigned

Reasons to Learn Java Programming

Java is one of the best programming languages built. In the last 20 years, Java has proven it.
This article will give you Reasons to Learn Java Programming, Two decades is a great
time for any programming language and Java has gained strength on every passing day.
Although Java development slows down many times, Java has responded well. Prior to Java 5
performance improvements with Java 6, and Google's choice of choice for Android app
development, Java, as a front-line programming language, with tremendous changes in Enam,
Generics, and Autoboxing in Java 5.

Many computer science graduates often have a question, which is the best programming

language to start with? which language should I learn to begin with? shall I learn Java? etc.

Well, it varies to the definition of your best programming language, if it's famous then obviously
Java outscores everyone, even C, which is there for almost 50 years.

If it is in terms of job opportunities, then Java outsources to everyone again. You can get the
opportunity for tons of jobs by learning the Java programming language, you can develop core
Java-based server-side applications, J2EE Web and Enterprise applications, and even for
Android-based mobile application development. Can go.

1) Java is Easy to learn

Many people would be surprised to see this seems to be one of the top reason for learning
Java or considering it as the great programming language, but it is. If you have a steep
learning curve, it would be not easy to get productive in a short span of time, which is the
case with many of the professional project.

Java has combined with English like syntax with minimum magic characters e.g. Generics

angle brackets so that it is easy to read Java program and learn quickly.

When a programmer is familiar with initial hurdles with installing JDK and setting up PATH
and understand How Classpath works, it's pretty easy to write a program in Java.

3) Java has Rich API

Another reason for Java programming language's great success is it's Rich API and most
importantly it's highly visible because come with Java installation.

As a newcomer started Java programming, I used to code Applets and those days Applets

provides great animation capability, which amazes new programmer like us, who are used to
code in Turbo C++ editor.

The Java programming offers API for I/O, networking, utilities, XML parsing, database

connection, and everything. Whatsoever left is covered by open source libraries like

Apache Commons, Google Guava, Jackson, Gson, Apache POI, and others.

4) Powerful development tools e.g. Eclipse, Netbeans
You do not believe but, Eclipse and Netbeans have played a big role to make Java
one of the best programming languages. Coding in IDE is a pleasure, especially
if you have coded in another platform like DOS Editor or Notepad.

They help in code completion as well as provides the powerful debugging capability,
which is crucial for real-world development. With the help of Integrated Development
Environment (IDE)  Java development seems much easier, faster and fluent. It's easy
to find, refactor and read code using IDEs.

Apart from IDE, Java platform also has many other tools e.g.. Maven and ANT for
building Java applications, decompilers, JConsole, Visual VM for monitoring Heap
usage etc.

5) Wonderful Community Support

A strong and thriving community is Java programming language and the biggest strength
of the platform. No matter how good a language is, it will not survive, if there is no
community to support, help and share their knowledge.

Java is very fortunate, there are lots of active forums, stack overflows, open source
organizations and many Java user groups that help everything.

Community is helping beginners, advanced and even expert java programmers. Java
actually promotes community habit withdrawing and giving. Lots of programmers, who
use open source, contribute in the form of a commutator, tester etc.

6) Java is Everywhere

Surely, Java is everywhere, it's on the desktop, it's on mobile, it's on the card, almost
every place and so is Java programmers. According to me, Java programmer
outnumber any other programming language professional.

Though I don't have any data to back this up, it is based on experience. This huge
availability of Java programmers is another reason, why organization prefers to choose
Java for new development than any other programming language.

Having said that, programming is a very big as well as large  field and looking at C and
UNIX, which is still surviving and even stronger enough to live more 20 years, Java
also falls in the same league.

Though there are a lot of talks about functional programming, Scala, and other JVM
languages, they need to go a long way to match community, resources, and popularity
of Java.

Introduction of Java

Two-part introduction to the Java programming tutorial is for software developers who are
new to Java technology. Work through both rising and moving parts with object-oriented
programming (OOP) and real-world application development using Java-language and platform.

 Java is a simple, robust and secure programming language. Here are the key features of Java:

This first part is a step-by-step introduction to OOP using Java language. The tutorial starts with
an overview of the Java platform and language, followed by instructions for setting up a
development environment, combined with the Java Development Kit (JDK) and the Eclipse IDE.
After getting acquainted with the components of your development environment, you start learning
basic Java syntax.

Prerequisites

This tutorial is for software developers who are not yet experienced with Java code or the Java
platform. The tutorial includes an summary or you can say overview of OOP concepts.

System requirements

To complete the exercises in this tutorial, you will install and set up a development environment
consisting of:

JDK 8 from Oracle

Eclipse IDE for Java Developers

Java platform overview

Java technology is mainly used to develop and make applications for a hige range of environments,
from consumer devices to heterogeneous enterprise systems. In this section, get a high-level view
of the Java platform and its components.

Many Java developers are constantly referring to the official Java API documents called Javadoc.
Three locations are planned in Javadoc. The top left lane shows all API packages, and the bottom left
shows lessons for each set. The main panel shows the details for the currently selected package or
class. For example, if you click java.utilpackage in the top left, then click the ArrayList class below, you see the details on the right side of the ArrayList, including the description of how to use it and its methods.

As any programming language, the Java language has own structure, syntax rules, and programming paradigm.

The Java language's programming paradigm is literally based on the perception of OOP, which the language's features support.

The Java language is a C-language derivative, as its syntax guideline look much like C's. For example, code

blocks are modularized into process and delimited by braces ({ and }), and variables are acknowledge before

they are used.

The Java compiler

Working on the Java platform, you write source code in .java files and then compile them. The compiler checks your code opposed to the language's syntax rules, then writes out bytecode in .class files. Bytecode is a set of guidelines targeted to run on a Java virtual machine (JVM). In this level adding of abstraction, the Java compiler differs from other language compilers, which write out instructions suitable for the CPU chipset the program will run on.

The JVM

During the runtime, JVM reads and interprets .class files. The program executes the instructions on the original hardware platform, for which JVM was written. JVM interprets the bytecode in the same way as the CPU interprets assembly-language instructions. The difference is that JVM is a piece of software specifically written for a particular platform. JVM is the heart of the Java language's "right-ons, run-anne-somewhere" theory.

Your code can run on any chipset for which an appropriate JVM implementation is available. JVM is available for major platforms such as Linux and Windows, and java language subsets have been implemented in JVM for mobile phones and Hobbit chips.

The garbage collector

Rather than forcing you to keep up with memory allocation (or use a third-party library to do so), the
Java platform gives data management out of the box. When your Java application creates an object
instance at during time, the JVM naturally allocates memory space for that object from the heap— a
pool of memory set aside for your program to work or use. The Java garbage collector runs in the
background, keeping track of which objects the application no longer needs and reclaiming memory

Java Interview Questions

In this Java Interview Questions blog, I am going to show you the list of some of the 

most important Java Interview Questions and Answers which will set you apart in the interview process. Java program is used by approx 10 Million developers worldwide 

to develop applications for 15 Billion devices supporting Java. Also used to creator 

make applications for trending technologies like Big Data to household devices like

Mobiles and DTH boxes. And hence today, Java is used everywhere!

Java Interview Questions all you want to know about Java interviews

As a Java professional, it is essential to know the right buzzwords, learn the right technologies and prepare the right answers to commonly asked Java Interview Questions. Here’s a definitive list of top Java Interview Questions that will guarantee a breeze-through to the next level.

Q1. Why Java is platform independent?

Platform independent practically means “write once run anywhere”. Java is called so because of its byte codes that can run on any system irrespective of its underlying operating system.

Q2. Why java is not 100% Object-oriented?

Java is not 100% Object-oriented because it makes use of eight primary data types such as boolean, byte, char, int, float, double, long, short which are not objects.

Q3. What are constructors in Java?

In Java, constructor refers to a block of code which is used to initialize an object. It must have the same name as that of the class. Also, it has no return type and it is automatically called when an object is created.

There are two types of constructors:

Default constructor

Parameterized constructor

Q4. What is the difference between equals() and == ?

Equals() method is defined in Object class in Java and used for checking equality of two objects defined by business logic.

“==” or equality operator in Java is a binary operator provided by Java programming language and used to compare primitives and objects. public boolean equals(Object o) is the method provided by the Object class. The default implementation uses == operator to compare two objects. For example: method can be overridden like String class. equals() method is used to compare the values of two objects.

Q5. What is Polymorphism?

Polymorphism is briefly described as “one interface, many implementations”. Polymorphism is a features of being able to assign a different meaning or usage to something in different contexts – specifically, to allow an entity such as a variable, a function, or an object to have enough form. There are two types of polymorphism.

Q6. What is association?

Association is a relationship where all object have their own lifecycle and there is no owner. Let’s take an example of Teacher and Student. Multiple students can associate with a single teacher and a single student can associate with multiple teachers but there is no ownership between the objects and both have their own lifecycle. These relationship can be one to one, One to many, many to one and many to many.

Q7. What do you mean by aggregation?

Aggregation is a specialized form of Association where all object have their own lifecycle but there is ownership and child object can not belongs to another parent object. Let’s take an example of Department and teacher. A single teacher can not belongs to multiple departments, but if we delete the department teacher object will not destroy.

Q9. What is composition in Java?

Composition is again specialized form of Aggregation and we can call this as a “death” relationship. It is a strong type of Aggregation. Child object dose not have their lifecycle and if parent object deletes all child object will also be deleted. Let’s take again an example of relationship between House and rooms. House can contain multiple rooms there is no independent life of room and any room can not belongs to two different house if we delete the house room will automatically delete.

Q10. Why there are no concrete implementations of Iterator interface?

Iterator interface declare methods for iterating a collection but it’s implementation is responsibility of the Collection implementation classes. Every collection class that returns an iterator for traversing has it’s own Iterator implementation nested class.
This allows collection classes to chose whether iterator is fail-fast or fail-safe. For example ArrayList iterator is fail-fast whereas CopyOnWriteArrayList iterator is fail-safe.
