title: java for-each loop for partial array
body: <p>I know how to use the for-each loop to cycle through an entire array like so:</p>
  
  <pre><code>for(int d : arrayname){
      do something
  </code></pre>
  
  <p>But how do you use the for-each loop to cycle through a partial array, like the one I am trying to do is to use the for-each to cycle through only the months of May-October, i.e. [4] - [9] to calculate the heat index. Here is a snippet of my code that shows what I am trying to do:</p>
  
  <pre><code>// create array for KeyWestTemp
      double[] KeyWestTemp;
      KeyWestTemp = new double[12];
  
      // initialize array
      KeyWestTemp[0] = 70.3;
      KeyWestTemp[1] = 70.8;
      KeyWestTemp[2] = 73.8;
      KeyWestTemp[3] = 77.0;
      KeyWestTemp[4] = 80.7;
      KeyWestTemp[5] = 83.4;
      KeyWestTemp[6] = 84.5;
      KeyWestTemp[7] = 84.4;
      KeyWestTemp[8] = 83.4;
      KeyWestTemp[9] = 80.2;
      KeyWestTemp[10] = 76.3;
      KeyWestTemp[11] = 72.0;
  
      // create array for KeyWestHumid
      int[] KeyWestHumid;
      KeyWestHumid = new int[12];
  
      // initialize array
      KeyWestHumid[0] = 69;
      KeyWestHumid[1] = 67;
      KeyWestHumid[2] = 66;
      KeyWestHumid[3] = 64;
      KeyWestHumid[4] = 66;
      KeyWestHumid[5] = 69;
      KeyWestHumid[6] = 67;
      KeyWestHumid[7] = 67;
      KeyWestHumid[8] = 70;
      KeyWestHumid[9] = 69;
      KeyWestHumid[10] = 69;
      KeyWestHumid[11] = 70;
  
      // for-each loop for calculating heat index of May - October
  </code></pre>
  
  <p>[0] is January and [11] is December</p>
