java - int cannot be dereferenced compilation error -

i getting error when try compile code saying

int cannot dereferenced

what causing it? here code using:

class {      public static void main(string str[]) {          int system=22;               system.out.println(system);     }  }

by writing

int system = 22;

you hiding class java.lang.system. when try do

system.out.println(...

the compiler thinks want have access varilable out of int doesn't have primitive type.

you write

int system = 22; system.out.println(system);

variable names should start lowercase anyways.

And
