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.

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++)
		System.out.println("\nSum of the numeric values:"); 	

Sample Output:

Input some text and numeric values:

Directory Content:

Java allows you to get the names of all subdirectories and files in a folder as an array, which can then be sequentially viewed.

import java.io.*;
public class ListContents {
  public static void main(String[] args) {
    File file = new File("//home//user//Documents/");
    String[] files = file.list();
    System.out.println("Listing contents of " + file.getPath());
    for(int i=0 ; i < files.length ; i++)
