Question

1. Put a JTextField in the north of the JFrame along with a JLabel that says: Year

2. Put a JSlider, vertically in the east side of the JFrame

   1. Have the JSlider range from 1990 to 2019
   2. Have the JSlider labeled Choose Year
   3. Add a ChangeListener to the JSlider
   4. Have the JSlider's value displayed in the TextField

   Hints

   1. to get the JSlider to be vertical, make the JSlider's orientation JSlider.VERTICAL.
   2. label the JSlider
      1. tell the JSlider to set the tick spacing:setMajorTickSpacing(4), and setMinorTickSpacing(2)
      2. tell the JSlider to make the tick marks show up: setPaintTicks(true)
      3. tell the JSlider to make the labels show up use setPaintLabels(true)
   3. for the changeListener to work, the class has to implement the ChangeListener interface. If the class implements more than one interface, they should be noted in a comma seperated list.
   4. the changeListener has to have a stateChanged method which takes a ChangeEvent object as an argument.
   5. The int returned by the slider can be converted to a string by concatenating it with the empty String as in:  "" + value

3. Have typing in the TextField change the JSlider.

   Hints

   1. The value from the TextField is obtained as a String. To get an int use Integer.parseInt()

4. Add JRadioButtons with labels that are color names

   1. Group the JRadioButtons into a ButtonGroup
   2. Hook your JRadioButtons to your program (use addActionListener()) so that the JFrame's background color is changed to the color chosen with the JRadioButton

   Hints

   1. The ButtonGroup just coordinates the buttons so, when one is pressed, the others turn off.
   2. Use setBackground() to set the JFrame's color. If setting the JFrame's color doesn't work for you, try setting the background color of each of the JPanels you have.
