It doesn t work because you didn t attach the ScrollPane to the JFrame   Also  you don t need 2 JScrollPanes   JFrame frame   new JFrame   Test    JTextArea textArea   new JTextArea   Test     JScrollPane scroll   new JScrollPane  textArea      JScrollPane VERTICAL SCROLLBAR ALWAYS  JScrollPane HORIZONTAL SCROLLBAR ALWAYS    frame add scroll   frame setVisible  true

A scroll pane is a container which contains another component  You can t add your text area to two different scroll panes  The scroll pane takes care of the horizontal and vertical scroll bars   And if you never add the scroll pane to the frame  it will never be visible   Read the swing tutorial about scroll panes
