How to write java program without using main method?

Answer 1

Java program without main

We need a main method for executing a program.

But YES we can write a program without using main() method.

TRICK 1 of 2 :: while writing applets in java we don't use main... we use init() method instead.
TRICK 2 of 2 :: using 'static' we can write a program whic will execute successfully and output the desired message on screen. Here it is :: class Mohit{ static { System.out.println("This java program has run without the main method"); System.exit(0); } } -->save the program as Mohit.java to compile::javac Mohit.java (in command prompt) to run ::java Mohit(command prompt) output will be ::This java program has run without the main method

Whoa!!!!! we are done.

Answer 2

A Java program needs an entry point - a class with a main() method. This tells the JVM where to start executing code. Once you have such a program, it can invoke other classes, which don't need a main() method.

Answer 3

There can only be one entry point per program. The main method serves as that entry point and therefore cannot be overloaded.

Answer 4

you can not write a java program without using even single class..............
