Java Programming Help

I did the first two parts but keep running into problems on 3-4 Extend the program [login to view URL] used in the class to include the following: 1. Add two more colors, black and yellow, to the list of color choices for displaying the welcome message. 2. Add two more radio buttons, one for Extra Small to the left and the other for Extra Large to the right of the existing ones. Use size 8 for extra small and 40 for extra large to display the welcome message. 3. Add a label Select a type style and a group of three radio buttons right above the reset button to allow a choice of three type styles, plain, boldfaced, and italic. Set the initial type style to plain. When one of the radio buttons is selected, the welcome text should be changed to the corresponding type style. 4. Modify the action listener for the Reset button so that when it is clicked, the display settings are reset to their initial values and the welcome message is displayed in the initial settings. 5. Add an Exit button next and to the right of the Reset button. When the Exit button is pressed, your program should terminate in the same way as when the window closing box is clicked.
