Handling Exceptions : Exception « Development « Java Tutorial






public class MainClass {
  public static void main(String[] args) {
    int i = 1;
    int j = 0;
    try {
      System.out.println("Try block entered " + "i = " + i + "j = " + j);
      System.out.println(i / j); // Divide by 0 - exception thrown
      System.out.println("Ending try block");
    } catch (ArithmeticException e) { // Catch the exception
      System.out.println("Arithmetic exception caught");
    }
    System.out.println("After try block");
    return;
  }
}
Try block entered i = 1j = 0
Arithmetic exception caught
After try block
