Answer 5

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

Answer 6

Use JOptionPane inside try catch

Answer 7

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

Answer 8

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

Answer 9

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
