Answer 1

I don't know your level of expertise.



A radiobutton is an XOR by design -- 1 choice out of many.

A checkbox is -- 1 stab or multiple stab from the choices.



Without knowing what you know, maybe you should use a long String of dot. The dots paralell the same number of checkboxes you have. The .setName of your button widgets are cleverly designed as rb0... rb1...rb2, rb3. Use the numeric after indexOf("b"). That numeric as a decimal value changes a dot into your 2, or 3, or 4, whatever you think the checkbox answer is worth, but you replace dot with decimal-comma.



At the end of PgmQuest

String[] qPts = dots.split(",");

Answer 2

Remember to test each function. Read the error message and check the line numbers that are listed.

Then you had better get your Java manual and class notes out and get THINKING ! How do you expect to learn when other people do your homework for you.
