JTextField textField = new JTextField(); textField.setMinimumSize(new Dimension(200, 20));This code will set the minimum size of the text field to 200 pixels by 20 pixels. The setMinimumSize method takes an instance of the Dimension class as its argument. This method is used to ensure that the text field is not made smaller than the specified size. If the user tries to resize the text field to a size smaller than the minimum size, the text field will remain at the minimum size. Package library: javax.swing
