Write a Java program to read two integers a and b. Compute a/b and print, when b is not zero. Raise an exception when b is equal to zero.
1 package program3.exception;
2
3 public class Division {
4 private float n1;
5 private float n2;
6
7 public Division(float n1, float n2) {
8 super();
9 this.n1 = n1;
10 this.n2 = n2;
11 }
12
13 public float computeDiv() {
14 if (n2 == 0) {
15 throw new ArithmeticException("/ by zero");
16 } else {
17 return (n1 / n2);
18 }
19 }
20}
21
22package program3.exception;
23
24import java.util.Scanner;
25
26public class ExceptionDemo {
27
28 public static void main(String[] args) {
29
30 Scanner s = new Scanner(System.in);
31
32 System.out.println("Enter numerator: ");
33 int n1 = s.nextInt();
34
35 System.out.println("Enter denominator: ");
36 int n2 = s.nextInt();
37
38 Division div = new Division(n1, n2);
39
40 try {
41 float result = div.computeDiv();
42 System.out.println("Result: " + result);
43 } catch (ArithmeticException e) {
44 e.printStackTrace();
45 }
46
47 }

49} |
OUTPUT :
Run 1:
Enter numerator:
2
Enter denominator:
0
java.lang.ArithmeticException: / by zero
at program3.exception.Division.computeDiv(Division.java:15)
at program3.exception.ExceptionDemo.main(ExceptionDemo.java:20)
Run 2:
Enter numerator:
4
Enter denominator:
2
Result: 2.0
