title: how to make jtextfield text disappear when tabbed into (Netbeans)
body: <p>I'm working on a gui that has multiple textfields that the user enters data into.  When the program opens, I have the instructions for what the user is supposed to enter into the textfield set as the "text".  I have it set to when user clicks textfield, the text will disappear, but I can't figure out how to get it to disappear when tabbed over into the next jtextfield.  I want the user to be able to click on the first textfield, and never have to use the mouse again, but also without having to go crazy on the backspace or del.  Thanks</p>
