Question Description :

What You Will Learn Basic button tracking Implementing Action Listeners Deliverables app-Java (initial application) MainFrame.java (external JFrame) A Java class for the control panel, that will contain the 2 new panels, using a layout. . A Java class for the Panel that will display the group's name and group's average GPA . A Java class for the Panel that will display names and semester GPAs of the 4 students in a group. . group java and student,java (a working version from previous labs, no changes needed). Students should apply consistent indenting in all submissions. This can be done via the NetBeans Source menu. Contents You will start with a working version from the previous lab. All requirements are still the same including "You will create only one group object g1 in this assignment. There will be only one statement group g1 new group!..);, in the whole application." Additional requirements are below. The ActionListener will be implemented in the ControlPanel, the external panel that contains the other two panels. A ceetainer panel with a border layout It has two panels. The ActionListener will be implemented here A panel with 3 buttons displaying estracted from a group object
