Need help with Java program

// Method to get a valid int from the user utilizing getInput entered via the keyboard

@SuppressWarnings({ "resource", "unused" }) // instruct the compiler to suppress leakage warning

\ im actally suppose to put private static boolean startGame() here But im having a hard time implementing the methods in this part of the program

private static int getInput() { Scanner sc = new Scanner(System.in); System.out.print("Enter a number between -64 and 64: "); int userGuess = sc.nextInt(); while (userGuess < MIN_NUM || userGuess > MAX_NUM) { System.out.println("Sorry, that's not a valid number. Please enter a number between -64 and 64: "); userGuess = sc.nextInt();

    // Giving the user hints if they guess the wrong number 
    if (userGuess > SECRET_NUMBER) {
        System.out.println("Hint: The number you are looking for is lower than your guess.");

    } 
       else if (userGuess < SECRET_NUMBER ) {
        System.out.println("Hint: The number you are looking for is higher than your guess.");

       }

    }
    return userGuess;
