java inputDialog

[sabi]

How would you read single character from JOptionPane class:

import javax.swing.JOptionPane;


for example:

response = JOptionPane.showInputDialog("are you having fun? (Y=yes, N=no)");


So how would you read if the user entered Y or N

[Fou-Lu]

showInputDialog returns a string, so you'd use response.equals() in order to determine what was entered.

This is what I got but im getting an error in the if statements, so can someone help me fix this?


import java.util.Scanner;

public class Alpha
{
public static void main(String[] args)
{
String = name1;
String = name2;
String = name3;
Scanner keyboard = new Scanner(System.in);

System.out.println("Enter name one");
name1 = keyboard.nextLine();
System.out.println("Enter name two");
name2 = keyboard.nextLine();
System.out.println("Enter name three");
name3 = keyboard.nextLine();

if(name1.compareTo(name2) < 0) && (name1.compareTo(name3) < 0) && (name2.compareTo(name3) < 0)
{
System.out.println(name1 + name2 + name3);
}
else if(name2.compareTo(name1) < 0) && (name2.compareTo(name3) < 0) && (name1.compareTo(name3) < 0)
{
System.out.println(name2 + name1 + name3);
}
else if(name3.compareTo(name1) < 0) && (name3.compareTo(name2) < 0) && (name1.compareTo(name2) < 0)
{
system.out.println(name3 + name1 + name2);
}

}
}
