In Java

I'm using the Eclipse IDE and am not able to get thisapplication to write to the file or change the color or exit theprogram. When options isselected and date & time are selectednothing happens. This is the same for all menu options. How do Iget this to work? This is the assignment:

Create a user interface that has a top bar that includes a menu.The menu should have four items.

• When the user selects the first menu option, then the date andtime should be printed in a text box.
• When the user selects the second menu option, then the text boxcontents should be written to a text file named "log.txt."
• When the user selects the third menu item then the framebackground color changes to random color hue of the color green.See https://www.w3schools.com/colors/colors_picker.asp (Linksto an external site.)
• When the user selects the fourth menu option then the programexits.

Is anyone able to help me to get this working? This isthe code I can't get to work properly.
