## 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
