    • B. JTextArea

    • C. JPanel

    • A. In the center of the desktop

    • B. In the same spot where the last application appeared

    • C. In the upper-left corner of the desktop

Answers

  • 1. B. JTextArea requires a container to support scrolling, but it is not a container itself.

  • 2. C. Any component can be added to a Scroll pane, but most are unlikely to need scrolling.

  • 3. C. This is a trick question. Calling setSize() has nothing to do with a window’s position on the desktop. You must call setBounds() rather than setSize() to choose where a frame will appear.
