Is the Main method must needed in a Java program?

Question

Is the main method needed to write a java program?

This is my code:

package example;

public class HelloWorld {

    public HelloWorld() {

    }

    public String getHelloWorld() {

        return "Hello From Java!";
    }
}

It shows an error at compilation:

java.lang.NoSuchMethodError: main
Exception in thread "main"

Answer 1

Without a main method you application will have no entry point. Yes, it is required for any executable program.
