.Add a TabbedPane to the GUI.The TabbedPane should have 2 tabs.The first Tab should be say Student GUI.The second Tab should ready Hello World and can have anything.Maybe just add one JLabel that says Hello World.

Rebuild the StudentGUI class without using Layout Managers.Maybe call ne class .You will not need to build 3 separate classes for this one.Just one class called StudentGUINoLayouts.Add all components in the appropriate locations.
