Question

java programming

1.Create a simple SWING Form to Display Student Data.The top part of the form should say “Student Information”.The middle part of the form will contain labels and textFields; one each for ID, FirstName, LastName, Email and GPA.The bottom part should have 5 Buttons that read “Find”, “Insert”, “Delete”, “Update” and “Exit”.

2.Add a few neat SWING features, like tooltips, borders, colors, etc. Also the Exit button should work and the “X” at the top right of the Window should also close the Application. Make it so that when the User clicks on the Exit Button, a MessageBox Window popup and ask the User if they are sure that they want to exit. If they say “Yes”, then Exit the App.
