title: How to use an output from an array and then sum all of its number in Java?
body: <p>I want the code to take the data from the array and then show the sum of the number from it, but I hit the wall.</p>
  
  <pre><code>public class StringBuffer{
  public static void main(String[] args) {
    countTo_N_Improved();
  }
     private final static int MAX_LENGTH=30;
     private static String buffer = "";
     private static void emit(String nextChunk) {
          if(buffer.length() + nextChunk.length() &gt; MAX_LENGTH) {
          System.out.println(buffer);
          buffer = "";  
     }
     buffer += nextChunk;
   }
    private static final int N=100;
    private static void countTo_N_Improved() {
    for (int count=2; count&lt;=N; count=count+2) {
       emit(" " + count);
       }
    }
  }
  </code></pre>
  
  <p>and this is the output</p>
  
  <pre><code> 2 4 6 8 10 12 14 16 18 20 22
  24 26 28 30 32 34 36 38 40 42
  44 46 48 50 52 54 56 58 60 62
  64 66 68 70 72 74 76 78 80 82
  </code></pre>
  
  <p>I want the output to become like this</p>
  
  <pre><code> 2 4 6 8 10 12 14 16 18 20 22
  24 26 28 30 32 34 36 38 40 42
  44 46 48 50 52 54 56 58 60 62
  64 66 68 70 72 74 76 78 80 82
  
  And the sum of the number from the array is 1722
  </code></pre>
  
  <p>Many thanks.</p>
