Java assignment, input selection

Question

I need help with my code: I'm brand new to Java

How do I get the string "user" variable to display my choice after I've entered the choice?

import javax.swing.JOptionPane;                 
import java.util.Scanner;
public class Assignment {
    public static void main(String[] args) {
        // TODO code application logic here
        Scanner input = new Scanner( System.in );
        String me = JOptionPane.showInputDialog("Please input name!");
        System.out.println("Your name is: " + me);
        String user = JOptionPane.showInputDialog("Please enter your choice!");
        System.out.println("Your choice is: " + user);
        JOptionPane.showMessageDialog(null, "Your choice is: " + user);

            if(user.equals('1'))

            JOptionPane.showMessageDialog(null, "Username" + me + user);
    }  
}

you're pretty close already. look in JOptionPane class

Use double quotes when comparing strings

 if(user.equals("1"))  // double quotes

            JOptionPane.showMessageDialog(null, "Username" + me + user);

That hasn't worked. It still wont display the message I want when I type 1 into the input box :/

It works for me. I used you exact code, replacing the single quotes with double quotes. It pops up a message "usernamepaul1" "Username" + me + user. That's how you have it. You should add spaces for the message to be more clear "Username " + me + " " + user

You need to press ok again after the user message displays, to see the next message

I typed in Paul for the first dialog, the 1 for the second dialog. Then a dialog pops up showing 1, I press Ok, then another dialog pops up showing '"usernamepaul1"`. Works.

If you don't want the user number message dilaog to pop up, just delete this line JOptionPane.showMessageDialog(null, "Your choice is: " + user);, that the dialog popped up will show '"usernamepaul1"
