Java help for a beginner - making a quiz

[crystaline]

I am trying to make a quiz in java to help people to decide what classes will suit them in Uni.

On paper, it will look like a tree diagram, so that dependent on a person's yes/no answer to a question it will lead them down a different branch leading to an eventual conclusion.

My problem is this (I'm sure it's probably quite a beginner question, though it's currently troubling me a great deal!):

I'm having trouble calling the if/else methods purely on the basis of the yes/no answer. I can get it like a questionnaire so that it just runs through all the questions chronologically, collecting the answers, but cannot get it to call different methods depending on the answer given by the user.

Does that make sense?

Thanks for any help in advance!

I'm sorry if it was a little confusing. Yes, the code you posted is similar to what I've got down right now.
Questions along the lines of..
1. "Do you like a challenge? (answer yes/no)" --(if "yes" then call q.2, if "no" call q.3)
2. "Do you like scientific subjects? (answer yes/no)"
--(if "yes" then call q.4, if "no" call q.5)

Snippet below (please excuse any things you may consider basic/n00b in the following)

public String getRightForYou(String right){
String r = "";

if (right.equals("yes"))
r = "goto next method";

else if (right.equals("no"))
r = "goto other method";

else
r = "Please enter yes or no (in lowercase letters).";

etc.


I'm just not sure how to use a nested if statement in this circumstance.

Wow, thanks Una and Ladforce, that was exactly what I needed.

With much thanks to Una, I managed to construct the simple quiz (posted below). But it seems now we have to integrate radio buttons (??). Have been playing around with some bits and pieces I have found online but am unable to intergrate them properly. Any hints or tips?
