Variable is assigned but never accessed

Issue

I'm new to Java and trying to do a simple count operation in a for loop:

public boolean play(Matrix matrix){
       int dimension = matrix.getDimension();
       int count=0;
       for(int x=0;x<dimension;x++){
           for(int y=0;y<dimension;y++){
               count++;
           }
       }
       return true;
   }

The error I get is related to count and is as in the title: Variable is assigned but never accessed. The variable count should have been initialized outside the for loop and then accessed inside the for loop, I don't understand where the problem is located.

Solution

Like GriffeyDog wrote: You never use (read from) the variable count, you just assign to it. That was the problem.
