Explanation : public static void main(String args[])

What is the work of public static void main(String args[]) method in Java. Here is the explanation :

• public : The public method can be accessed outside the class
• static : We must have an instance to access the class method.
• void : There is no need by application to return value. JVM launcher do this with it exists.
• main() : It is the entry point for the java application.
• String args[] : It holds optional arguments passed to the class.

First Program in Java

Before writing java code, please be careful when you write the java code because it is case sensitive language. I will explain later about "String[] args".

class HelloWorld {

public static void main(String[] args){

System.out.println("My First Program:Hello World!");
