Modify your program so that it displays labels for each of the sliders as well as provides text fields to reflect the values of the sliders.

example:

For the text fields, create a subclass of JTextField that restricts input to integers ranging from 0 - 255. Implement behavior so that when the user inputs values, the UI is updated, including the sliders and the color panel.

3. Provide a way for other components to get the current color in JColorChooser for use in their own display. Provide a test class demonstrating this behavior. (Hint: You might consider making the currently displayed color an instance variable and exposing that variable to outside classes.) Something simple is fine:

4. Provide a way for users to close the program when they are done. be careful with leaving the color available for outside components.

5. Modify ColorLabel so that it displays the hexadecimal value of the current color.
