Finish Fifteen, as stated in the specification, being sure you have checked in your final,
fully-documented copy to the repository.
Written homework to do before week 4 (due before beginning of class on
Monday, Sept 24).
Answers are to be written in your own words! As usual, please bring hardcopy for
written answers to class to hand in on Monday.
1. Weekly reading. You may also want to refer to the Sun Java tutorial on Swing as
a reference.
2. (15 pts) Describe any three different LayoutManagers in Swing.
SOLUTION:
FlowLayout – adds components from left to right, top to bottom – default layout
manager for JPanel
BorderLayout – adds components in the regions North, South, East, West, and
Center. The region to add the component to must be specified when adding a
component
GridLayout – creates a grid with the specified number of rows and columns.
Unless a location is specified, the GridLayout will fill itself left to right, top to
bottom as components are loaded.
3. (10 pts) Describe any advantages of having a panel be a subclass of JPanel rather
than using JPanel as-is.
SOLUTION:
Extending JPanel allows the developer to reuse all protected and public members
of the JPanel class, rather than rewriting the code. Also, it allows the user to
customize the JPanel by adding new fields/methods, etc.
