Javase Mouse event class (MouseEvent) implementation

{Related Information}
A mouse event class (MouseEvent) is a mouse action event that occurs in an assembly, such as pressing the mouse, releasing the mouse, clicking the mouse, entering or leaving the component's geometry, moving the mouse, and dragging the mouse. Mouse events are triggered when the mouse is moved to an area or when the mouse clicks a component. Using mouse events, you must add an event handler for the MouseListener interface to the component that contains the following 5 methods:
void mouseclicked (MouseEvent e): Occurs when the mouse is clicked in the area
void mouseentered (MouseEvent e): Occurs when the mouse enters the area
void mouseexited (MouseEvent e): Occurs when the mouse leaves the area
void mousepressed (MouseEvent e): Occurs when the mouse is pressed in the area
void mousereleased (MouseEvent e): Occurs when the mouse is released in the area

Achieve
During the experiment, in the panel area, you can clearly see the difference between clicking and pressing. Click to release immediately is a click to get the location information.
If you press not to release, move after a while, then release, will not get the location information.
