Question

I got the problem with the following error:

Syntax error on token “;”, { expected after this token
Syntax error, insert “}” to complete EnumBody

public enum ImpNoise {
  INSTANCE;

   private int p[] = new int[512];


   for(int i = 0; i < 256; i++) {

   }

}

I stripped the whole class down to the bare minimum as you can see above.
I figured out that the for loop is causing the problem.
But i really don’t get it, it looks ok right?

Answer 1

You need to place code in a code block. Only initialisers for fields can avoid this.

What you may have intended was

public enum ImpNoise {
   INSTANCE;

   private final int[] p = new int[512];

   // either
   {
       for(int i = 0; i < 256; i++) {

       }
   }
   // or
   private ImpNoise() {
       for(int i = 0; i < 256; i++) {

       }
   }
}
