Why is the main method static?

I've often pondered over this subject. I know the main method has a special signature the JVM looks for, but why is it static?
Dunno probly cus thats how they want it to work.

Primarily so that the JVM doesn't have to instantiate your controlling class to get an entry point into the program.

>So that would take longer than having a main method that does the same thing?
If main isn't static then an object of the class must be created first (unless the JVM wants to break its own rules, which isn't unheard of). By requiring main to be static, the environment avoids an unnecessary step. So yes, it would take slightly longer.
