Java Program that reads a line of integers and then displays each integer and sum of all integers

Program

// import java.util.Scanner;

// import java.util.StringTokenizer;

import java.lang.*;

import java.util.*;

class Tokenizer

{

 public static void main(String args[])

 {

   int n sum=0;

   String k;

   Scanner s=new Scanner(System.in);

   System.out.println("Enter line of integers")

   String s1=s.nextLine();

   StringTokenizer s2=new StringTokenizer(s1);

   System.out.println("Total number of Tokens: "+s2.countTokens());

   System.out.println("Elements are ");

   while(s2.hasMoreTokens())

   {

     k=s2.nextToken();

     n=Integer.parseInt(k);

     System.out.println(n);

     sum=sum+n;
   }

  System.out.println("Sum value is "+sum);

 }
}

Result

Enter line of integers

1 2 3 4

Total number of Tokens:4

Elements are

1

2

3

4

Sum value is 10
