8.3 TERMINATING A PROGRAM USING SYSTEM.EXIT()
System.exit() is a method in Java used to terminate the currently running program.
There are two types of terminations using System.exit():
1. To exit normally, we use System.exit(0).
2. To have an abnormal exit, System.exit(1) or System.exit(-1) or any other non-zero value is used.
Program 12 Input a number and print the square of the number. If the number is 0 then it will print an
error message.
1 import java.util.*;
2 class square
3 {
4 public static void main()
5 {
6 Scanner sc = new Scanner(System.in);
7 int n,sq;
8 System.out.print("Enter the number: ");
9 n = sc.nextInt();
10 if (n == 0) {
11 System.out.println("Number should not be 0");
12 System.exit(0);
13 }
14 sq = n*n;
15 System.out.println("Square of " + n + " = " + sq);
