title: Appending text in Java's JTextArea
body: <p>I have a problem with my text area.</p>
  
  <p>I use <code>jTextArea1.append("cleverly amusing");</code> to add the text.. </p>
  
  <p>FIRST APPEND:</p>

  <p>then I use <code>jTextArea1.append("a fight");</code> to add the next text. </p>
  
  <p>SECOND APPEND</p>

  <p>What I Really want is to replace the "cleverly amusing" to "a fight". But I cannot do it. I tried to use the <code>jTextArea1.removeAll();</code> but there's no effect. How can I remove the "cleverly amusing" so that I can append the "a fight" to the first line.</p>
  
  <p>NOTE: "WORD HINT" is fixed...</p>
  
  <p>What can I do?</p>
