Learn the Basics of JAVA

Introduction To Java Programming:

Java was created by James Gosling in 1991 and later it was developed by Oracle Corporation.

Why Java?

• Simple programming language
• Writing and debugging is easy
• Compiling a program is very easy in java

Features of Java:

The following are the features of java. They are:

Simple

Robust

Object-oriented

Secure

High performance

Multithreading

Platform independent

Portable

Simple:

Java Training Institute in chennai is easy to learn and also it’s a High-level programming language

Robust:

Java is reliable because it checks the error quickly. Even it check the complex program and solve the error, that’s why it’s a robust language.

Object-Oriented:

It is a way of organizing programs as a collection of objects.

Four Main Concepts of Object-Oriented Language are:

Encapsulation

Inheritance

Polymorphism

Abstraction

Secure:

Core Java Training in Chennai has lots of security features and by default, this feature is available in java

High-performance:

It operates on full speed.we can get a solution for our program easily.java program is converted to bytecode.so it’s a performance also increased.

Multithreading:

Java Training Institute in chennai. Multithreading is a Java feature that allows execution of multiple threads.

Platform independent:

A compiler converts Java source code into bytecode and that bytecode was executed by jvm. JVM might different for another operating system, but its performance and solution is the same.

Portable:

Java code is written on one operating system can run on another operating system

Java Terms:

JDK

JVM

JRE

Java Development Kit:

The JDK is the Java Development Kit and it also includes JRE. In order to create, compile and run Java program,JDK has to be installed.

Java Runtime Environment:

The JRE is the Java Runtime Environment and its a part of JDK.By installing the JRE only you can run a program but it won’t compile the program.it contains all the library jar files.

Java Virtual Machine:

JVM is the Java Virtual Machine. the JVM has the primary javac compile and the compiler will convert the Java source code into bytecode .because the machine doesn’t understand the .class file, so it has to be converted into bytecode then the results of the program will be displayed in the console.

By learning the Core Java Training in chennai basics it is important to know the functions of Java execution and it's also take a major role play in the execution time. for that java basics is necessary.

So we have to know what happening in the JVM while executing the program and what is the purpose of installation of jdk and jre.
