oop - What will happen if I declare main in java non-static -


i started learning java , first doubt encountered main declared static in java jvm don't have initialize class accessing main. question why jvm avoid initializing class has main? cost incur if declare main non-static?

the compiler treat instance method, i.e. won't able execute directly java yourclass.

but question why jvm avoid initializing class has main?

because there's no need of initializing class, since cannot entry point application. @ runtime, jvm check presence of public static void main(string[] args) method , if there one, initialize class (i.e. execute it's static blocks, initialize it's static variables , on). however, if class considered in invalid being entry point application, operation break.
