JFrame: Why Is A Container Necessary?

Skar.2007May 17 2024

JDK 21 | swing

Hello everyone.

If you can directly insert the Components (for example: JButton, JTextField,...) in a JFrame, why would it be necessary to previously insert a Container such as JPanel and only insert the Components on top of it?

Thank you very much already.

A kind of organizing the UI, usually you will have many controls to display to the user , if you are going to display all of these items in the JFrame only your code will become longer and unmanageable , and maintaining it will need too much efforts and time as well.

Another reason is making code reuse , for example if you are going to make and EmployeeSalaryPanel

which will display only employee salary related info, this panel can be used for the HR department's users screen , and it may also be used in another screen for the Accounting department's users.
