Hello everyone,
I am using Java language for one of my project that I have to submit within some time. I want to show an error using joptionpane error message when user accidentally clicks on a button.
Can someone tell me how to use joptionpane to display such a message?
You can use the code below if you wish to show an error message in your project:
Make sure that you import the libraries in your source code. Also, ensure that you add the code for button click which I have skipped here.
Type the above source code into your program and execute it after compiling.
Your error message will somewhat look like this:
