How can I add the load function to this code as well as when I save these files of persons how can I make it so I can view the entries of persons I saved as well as when I press the new button while I was creating a person how do I have it say save before when I try to create a new person and haven't saved that yet? So implement this in simpler terms Select "New." You should get the "Save first?" pop up

$$Say no

$,$

$$then load the file you just made.

View current list of entries import javax.swing.
