- 9. Other In thisassignmentwere usedfew extrajavafurthersuch as,<DefaulListModel>thatisa implementation of the ListModel thatextendsfromAbstractListModel. Thisallow store datatothe JList andthen display it.AlsoI use the ButtonGroupfurtherof java .The ButtonGroupclassis responsible tomake sure only one buttonis selected(bydeselectingothersinthe group). Conclusion OverthisassignmentIgota goodbasic knowledge of Javaprograming,whichwillactas a good foundationforcontinuingforthe Javasubject.
