If this code is an exact copy, it probably doesn't work because you didn't use the import keyword

Use JOptionPane inside try catch

You should use JOpationPane inside the try block then it will work otherwise it's throw an exception or an error

First line should be: import javax.swing.*; Are you doing it here? Using swing on sololearn isn't a good idea.

It's impossible, swing is about windows, buttons, while sololearn Java is just a console. But don't worry, it will be better for your skills to program on normal operating system.

Best practices : import specific class -> Import.java.swing.specificClass
