I have a query which is as follows:

I have 6 textfields & 1 submit button on one frame and I have implemented the validation checks on each textfield by writing all the coding using if else in the button, and when ever any one enters wrong data into any field , an error gets displayed using JOptionPane.showMessageDialog().

Now,my question is can i use try and catch over here . If yes, then should i need to write my own Exception class to handle such thing, or this idea is wrong?

thanks
regards.

You can throw an user defined exception when the input boxes are empty and then catch them to show the Dialog message.
