Java Tutorial : Java unchecked exception(ArithmeticException) |
/* * If you compile this code, it would compile * successfully however when you will run it, it would * throw ArithmeticException. That clearly shows that * unchecked exceptions are not checked at compile-time, * they are being checked at runtime. */ public class UnCheckedExceptionDemo1 { public static void main(String[] args) { int number1 = 10; int number2 = 0; /* * Since I'm dividing an integer with 0 it should * throw ArithmeticException */ int result = number1 / number2; System.out.println(result); } }
Exception in thread "main" java.lang.ArithmeticException: / by zero at UnCheckedExceptionDemo1.main(UnCheckedExceptionDemo1.java:19)
import java.util.Scanner; public class UnCheckedExceptionDemo2 { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Enter number1:\t"); int number1 = scanner.nextInt(); System.out.print("Enter number2:\t"); int number2 = scanner.nextInt(); scanner.close(); try { int result = number1 / number2; System.out.println(result); } catch (ArithmeticException arithmeticException) { System.out .println("Cannot divide an interger with zero." + "So please enter number2 value greater then zero."); } } }
Enter number1: 15 Enter number2: 0 Cannot divide an interger with zero.So please enter number2 value greater then zero.Click the below link to download the code:
