Cleaner Alternative to Nested Switch

Question

Hi,
I have some code that runs a simple wizard using YES_NO JOptionPane's.
The code started off relatively simple with only two questions e.g
switch (question1)
case yes
    switch (question2)
          case yes
              run command
              break
           case no
               display message
               break
case no
      run command
       break
}This has now grown into a five level nested switch statement, which apart from looking ugly, I am not looking forward to having to maintain it.
Is there an alternative solution to coding a long nested switch statement for this kind of application?
Im still fairly new to the language and principles so all Im looking for is a couple of pointers in the right direction.
Cheers

Polymorphism would be the preferred way.
Something like:interface Question {
    boolean ask();
class Question1 implements Question {
    public boolean ask() {
        // ask the question
        boolean yes = ...
        if (yes) {
            return new Question2().ask();
        // run command
        return yes;
class Question2 implements Question {
    public boolean ask() {
        // ask question
        boolean yes = ...
        if (yes) {
            // run command
        } else {
            // display message
        return yes;
}
