Lab 07: Java Graphics (Bonus lab) In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: ➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). о The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: о An input button to register your mouse to the drawing panel. ○ о о A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels.…
