title: Java: Get maximum value of variables
body: <p>I am trying to find the largest values of these three variables (aCounter, bCounter, cCounter) that has been calculated. Java does not like how I am putting them into the string. 
  Thanks in advance guys!</p>
  
  <pre><code>   double aCounter=0;
     double bCounter=0;
     double cCounter=0;
  
           { code to count occurrences of each character in text file }
  
     String lines = aCounter + bCounter + cCounter;
      String [] array = lines.split (" "); //splits with a space
      int largestInt = Integer.MIN_VALUE;
      for (String numberString : array )
      {
          int number = Integer.parseInt(numberString);
          if (number &gt; largestInt)
          {
              largestInt = number;
          }
      }
  bw.write ( largestInt );
  </code></pre>
