title: counting the number of zeros
body: <p>I'm trying to write a program that gets a .txt file that only has something like 10000010000010000010001</p>
  
  <p>I'm trying to count the number of zeros and output it like  5 5 5 3. I thought if I convert a string into a <code>double</code> or <code>int</code> I could write an <code>if</code> or <code>for</code> loop. </p>
  
  <pre><code>import java.util.Scanner;
  
  public class test1{
  
      public static void main(String[] args) {
  
          java.io.File test2 = new java.io.File("test3.txt");
  
          try
          {
             Scanner input = new Scanner(test2);
  
          while(input.hasNext())
          {
              String num = input.nextLine();
              System.out.println(num);
  
              double n = Double.parseDouble(num);
              System.out.println(n);
          } 
          }
  
          catch (Exception e){
              System.out.println("could not find file");
          }   
  
         }
  
  }
  </code></pre>
