Hi,

Let's say if I am trying to input a string, and I want to prevent people from just hittong the send button and send a null, what check should I check for?

The input is a string variable.

Example :

x = JOptionPane.showInputDialog("Enter 1st Integer: ");

Thanks and Rgds

Sorry left out something.

My next step is to convert the input string to a int variable. If people input character, the conversion will go hay-wire. How to by pass this problem as well?
