Why doesn't import javax.swing.JOptionPane work with the compiler provided by Sololearn?

Question

I cannot use, for example, the next structure:

String name;
name = JOptionPane.showInputDialog("What is your name?");

it should allow the user to read the question and type their name, but instead iht shows Time limit exceeded

Thanks

SoloLearn doesn't provide an advanced IDE for Swing and graphics, so my guess is they don't provide access to those packages.
