Basically what I am trying to do is have a user enter either a Y or an N and return an output depending on what they answered.

This is what I have so far.

CODE

import javax.swing.*;

public class fish

{
    public static void main(String[] args)
    {
    string input, y, n;

    do
    {
        input = JOptionPane.showInputDialog("Do you like Pie? Either type Y or N");
        if (input == "Y") System.out.println("I like pie too!");
        if (input == "N") System.out.println("Well pie doesn't like you either.");
    }
    }
}


the main questions are:
1. Is string the right thing to be using?
2. Is the input == "Y" syntax correct

any help would be greatly appriciated

thanks

seeing that its a char being entered, you could use a char variable. However i dont really see much of a problem using a string for a program this size. When you compare a string, you shouldnt be using ==. Strings should be compared using .equals
exp
CODE
if(input.equals("Y"))


or if you want to make sure that the input y is accepted, you can use .equalsIgnoreCase("y")

you should turn the second output to an else if statement, and then follow this with an else statement to print an error if one of these two inputs are not entered.
