how to execute a simple display without a main method

this example will show you how, i got this code from the net, and i hope someone will support this, i just like to share this tricky way on how to execure something WITHOUT A MAIN method

Code :

---

public class NoMain {
 
    static {
 
        System.out.println("No Main!");
        System.exit(0);
    }
}

---

i tried to run this in my IDE, but the JVM complies that the class dont have any methods
try to run it in a command - line.. you will see that it will execute normally like any other class with main

This is not good practise I have to say, usually you use the static blocks to initialise static variables.

tnx for letting me know that sir json... its been a while :),
i just got this from a trivia in other posts, i thought this one could be usefull , i was surprised that a user can execute a code without a main method, so i thought this is valid in java practices,,

Also static blocks are good for loading external DLLs

I had JNI in mind for Windows lol! I know its not cross- compatable but hey ho, its still true.

Perhaps I should have said, precompiled external libraries
