I'm trying to get some input using JOptionPane. I want the user to enter a string and if this string is equal to the string I'm looking for I want to execute some code.
The problem is I'm unsure how to do this. I've tried the following.

Doesn't it work for you?

If not can you post two sample strings that you are using?

Hi Friend !!. Its simple

Use showInputDialog() in JOptionPane to get String

showInputDialog() has different method signatures other than i have used. please see javadoc .

I'd change that to
, or at least

JOptionPane.showInputDialog returns null if the user presses Cancel, so your code would throw a NullPointerException if that woud occur.

Friend , I am not giving you the Exact Code.

I gave you an Example. you have to write events for that.

Please have a look on this

I know, but my warning is to prevent any unexpected errors when Michael just copies your little example and is not aware of the possible NullPointerException.
