  I'm having a little trouble with one of my exceptions. The following code is just a simple division of two integers. I have built two exception to handle an InputMismatch and divide by zero. What I want to happen is when there is an exception, I want the program to return to let the user enter more data. If there is no exception, I want the program to end. The problem occurs when I enter words instead of numbers to make the exception InputMismatch work. When this happens the program goes into an infinity loop and I have to kill the program. Can somebody please look at my code and let me know what I'm doing wrong?
  Also, do I need a throw for the InputMismatch?
  import java.util.Scanner; import java.util.InputMismatchException; public class P4Exceptions { public static void main(String[] args) { Scanner scan = new Scanner(System.in); int n1, n2; double r = 0; boolean continueLoop = true; // determines if more input is needed while ( continueLoop ) { try { System.out.println("Enter two numbers. I will compute the ratio:"); n1 = scan.nextInt(); n2 = scan.nextInt(); r = (double) n1 / n2; if (n2 == 0) throw new ArithmeticException(); System.out.println("The ratio r = " + r ); continueLoop = false; } catch ( ArithmeticException arithmeticException ) { System.out.println("There was an exception: Divide by zero. Try again\n"); } catch ( InputMismatchException inputMismatchException ) { System.out.println("You must enter an integer. Try again.\n"); } } } }
