It makes these suggestions based on the positions of the components that have already been placed in the form, while allowing the padding to remain flexible such that different target look and feels render properly at runtime.

Ensure that the manifest. To set component resizeability behavior: Because it uses a dynamic layout model, GUI’s built with the GUI Builder behave as you would expect at runtime, adjusting to accommodate any changes you make without altering the defined relationships between components.

Make certain to release the Shift key prior to positioning the second JLabel. The last thing we need to do is delete the placeholder text in the various components.
