Text Areas

• Use a JTextArea to show multiple lines of text
• You can specify the number of rows and columns:

  final int ROWS = 10;
  final int COLUMNS = 30;
  JTextArea textArea = new JTextArea(ROWS, COLUMNS);

• setText: to set the text of a text field or text area
• append: to add text to the end of a text area
• Use newline characters to separate lines:

  textArea.append(account.getBalance() + "\n");

• To use for display purposes only:

  textArea.setEditable(false); // program can call setText and append to change it
