I have a programming assignement that i have been working on for quite some time now. I need your guys' help. My assignement is to great a table with data in it. and it will have a combobox and 2 buttons to how it will be sorted( run the program and you'll see how its setup).The table will have a comboBox that includes the 4 headings. We have to use insertion and selection sorting. I have done some of the program, just need help on getting up and running good. There will also be two buttons (“0-9/A-Z” ) and (“9-0/Z-A”). The user will choose by which heading the table should be sorted and then press the button as to how it will be sorted. When that button is pressed the table will be sorted and appear correctly with the correct information for each person. As 2 of the headings are Strings and 2 are integers, you will need to make the sorting of the Last name and age a selection sort and the sorting of the First name and test score insertion sorts. Check out the code, thanks for the help guys.
