title: Why does the JScrollPane show up but not its scroll bar?
body: <p>Here is my code. The JScrollpanel shows up but now the scrollbar. I also can't use the scroll wheel if the text goes below the area.</p>
  <pre><code>JTextArea textArea = new JTextArea(&quot;Enter text here&quot;);
  textArea.setPreferredSize(new Dimension(100,100));
  textArea.setLineWrap(true);
  textArea.setEditable(true);
  textArea.setVisible(true);
  JScrollPane scroll = new JScrollPane(textArea, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
  JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
  
  //frame
  this.setTitle(&quot;GUI Practice&quot;);
  this.setLayout(new BorderLayout());
  this.setResizable(true);
  this.setSize(720,480);
  this.setLocationRelativeTo ( null );
  this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  
  this.add(scroll, BorderLayout.SOUTH);
  this.setVisible(true);
  </code></pre>
