In this article, we will list out reasons why do we use always “public static void main()” in Java

Why do we use “public static void main” only in Java ?

To start executing a Java program, the corresponding method should be “public static void main()

  • main : This is name of the method, which is used as a identifier by JVM to invoke or begin/start the execution of the program
  • static : instance methods are invoked only after instantiation; but static methods can invoked with class name like <Class-Name>.<static-Method-Name>
  • void : as the invoker of this method is JVM and it doesn’t need or expect any return value therefore it is void (as it indicate nothing to return)
  • public : This is access-modifier or visibility & highest visibility is public, which is accessible for everyone

Main.java

package in.bench.resources.sample;

public class Main {

	public static void main(String[] args) {

		System.out.println("Hello, welcome to Java world !!");
	}
}

Output:

Hello, welcome to Java world !!
