In this article we will learn to implement a Java program to display integers and their sum using StringTokenizer. A Java program is provided below which uses StringTokenizer class, reads a line of integers and then displays each integer and the sum of all integers.

Program is as follows:

import java.util.*;
class StringTokenDemo
{
	public static void main(String args[])
	{
			Scanner s = new Scanner(System.in);
			System.out.print("Enter a line of numbers: ");
			String input = s.next();
			StringTokenizer st = new StringTokenizer(input,"@");
			int sum = 0;
			while(st.hasMoreTokens())
			{
				int n = 0;
				n = Integer.parseInt(st.nextToken());
				System.out.println("Number is: "+n);
				sum += n;
			}
			System.out.println("Sum of the numbers is: "+sum);
	}
}

Input and output for the above program is as follows:

Enter a line of numbers: 2@3@1@4@5
Number is: 2
Number is: 3
Number is: 1
Number is: 4
Number is: 5
Sum of the numbers is: 15
