title: Concatenate auto generated strings in java with a space seperator in between
body: <p>I have a string array variable which values changes continuously. Random arrays are generated from it. This is what i have:</p>
  
  <pre><code>String trans = Utility.GetColumnValue(testdata[k], "suggest_text_2");
  </code></pre>
  
  <p>The <code>trans</code> value changes continuously. How can i concatenate it with the previous values? How can i print every value of <code>trans</code> as it changes continuously? Do i need to use any buffer?</p>
