Counting Loop Using Threads (Java)

Hi,

The following is a simple code to display a count of a loop of 100:

Code:

public class count {
  public static void main(String[] args){
   int count = 0;
   int i = 0;

   while (i < 100) {
	  i++;
	  count++;
	  }
   System.out.println("Number of values: " + count);
  }
}

I would like to use two threads to do the counting concurrently. The first thread starts every 3 seconds while the other one starts say every 5 seconds. Then display how many numbers each thread was able to count out of the 100. How do I accomplish this?

Any help would be truly appreciated!

 

The following is a basic code to read integers from a file:

Code:

import java.util.Scanner;
import java.io.*;

class FileReadingApp
{
  public static void main (String[] args) throws IOException
  {
    int count = 0;

    File file = new File("data.txt");
    Scanner scan = new Scanner( file );
    while(scan.hasNextInt())
    {
      double num = scan.nextInt();
      count++;
    }
      System.out.println("Number of integers is: " + count);
  }

}

Finding a multithreading solution for this problem using the loop example or the file example should be enough to get me started. Thanks!
