Introduction to using Java to implement the system tray function (with source code and screenshots)

How to implement the system tray function in Java.

Example

Project Package Structure

System Operation

The core logic of the application indicates that hiding in the tray is actually about hiding the form. That is, setVisible (false), and displaying the form is about setVisible (true ).

The project code is as follows:
