Without main

[maya700]

Hey guys,

I have a doubt. I read somewhere that a java program without main method may run!!!. Is that true??? if yes then how????

Thank you.

No and yes. The program that is started by the java command must have the main() method. I don't know a way to tell the java program to use another static method.
If you write an 'interface program' with a main, that program can create an instance of another class and optionally call any method in that class.

Another type of program not needing a main is an applet. In that case instead of being required to have a main, it is required to have an init method.

For an example,

class NoMainMethod
{
    static
    {
        System.out.println("this is a text");
        System.exit(0);
        
    }
}
