        Scanner kbScanner = new Scanner(System.in);
        int test = kbScanner.nextInt();
       
        if (test>=1&&test<=1000) {
            double []answer = new double[test];
            for (int i = 0; i < test; i++) {
                answer[i] = calculate(kbScanner.nextInt(),kbScanner.nextInt());
            }
           
            for (int i = 0; i < answer.length; i++) {
                System.out.println("Case "+(i+1)+":"+" "+(int)answer[i]);
            }
           
        }
       
    }

      return Math.pow((2*next),2)-Math.pow(next0,2);
   
    }

It is not guaranteed that the answer will fit into an integer. Use Long in java. When you are printing the solution just type cast it to Long instead of int. I think it will make sure your program gets accepted.
