How can you modify the contents of a JTextField?

Using setText()

To modify the content of a JTextField, the most appropriate option would be to use the setText() method. This method replaces any existing text in the field with the new specified text. The other options, such as append() and directly assigning a value, do not replace the existing text and can potentially cause confusion for the user. Using setTextField() is not a valid method for modifying the contents of a JTextField and therefore, is incorrect.
