Joptionpane showinputdialog without cancel button app
I have a series of of JOptionPanes pop up to get info from the user. However, if the user presses cancel, the machine gets an error which is prevented. I'm trying button catch this and force cancel user to make a choice and press OK. MY code doesn't showinputdialog do do this. Here are the two ways that I tried:.

I just dont understand why it doesnt work because joptionpane i made this simple program:. If you use the showInputDialog method, it either returns the String that was entered in the text field or else "NULL" joptionpane cancel was pressed, App in case cancel wish a User to force some input and not press Joptionpane, you could simple put it in a do-while loop like this: However if you use showOptionDialog without, and pass the "possibilities" array for the button, you would get three buttons with their corresponding headings as specified in the Array.
