Java Exercises: Sum of all numerical values embedded in a sentence

Java Basic: Exercise-236 with Solution

Write a Java program to sum of all numerical values (positive integers) embedded in a sentence.

Input:
Sentences with positive integers are given over multiple lines. Each line is a character string containing one-byte alphanumeric characters, symbols, spaces, or an empty line. However the input is 80 characters or less per line and the sum is 10,000 or less.

Sample Solution:

Java Code:

 import java.util.Scanner;
public class Main
{
    public static void main(String arg[])
    {
        Scanner in = new Scanner(System.in);
        int count =0;
        String tmp = "0";
		System.out.println("Input some text and numeric values:"); 
        char ch[]=in.nextLine().toCharArray();
        for(int i=0; i<ch.length; i++)
          {
           while(i<ch.length&&(Character.isDigit(ch[i])))
            {
                tmp+=ch[i];
                i++;
             }
           count+=Integer.valueOf(tmp);
           tmp="0";
            }   
		System.out.println("\nSum of the numeric values:"); 	
        System.out.println(count);
    }
}

Sample Output:

Input some text and numeric values:
5 apple and 10 orange are rotten in the basket

Sum of the numeric values:
15
