Thread: Can someone tell me why I keep getting a tie, no matter what I type in?

Hey guys I am trying to write this code to play rock, paper, scissors against the computer. No matter what letter I type in it converts it to 0 and also randomly gives the computer 0 and calls it a tie every time I try it.

/*  
    File Name: rockPaperScissorsGame
	Programmer: David Wheeler
	Purpose: Creates the rock, paper, scissor game. 
*/
import javax.swing.JOptionPane; // Needed for JOption class to recieve input.	
import java.util.Scanner; // Have to import in order to use the Scanner class.
import java.util.Random;  // Needed for Random class
public class rockPaperScissorsGame
{
	public static void main (String[] args)
	{
		int CT = 0;
		String user = "0";
 
		//First thing call the directions funtion to explain the game. 
		directions();
		//get the computers choice. 
		computersTurn(CT);
		//get the users choice.
		usersTurn(user);
		//Display the computers choice and the winner.  
		displayResults(user, CT);
 
 
 
	}
 
	public static void directions()
	{
	JOptionPane.showMessageDialog(null,"\nTo play the game you type R for ROCK, P for PAPER, or S for Scissors\n\n"+
	                   "A  winner  is selected according  to  the  following  rules:\n\n"+ 
						"*  If one player  chooses rock  and the other  player chooses scissors,\n"+		
      						"then  rock  wins, (The rock  smashes the  scissors.)\n\n"+ 
						"*  If  one  player  chooses  scissors  and the other  player  chooses  paper,\n"+ 
						    "then  scissors wins. (Scissors cuts  paper.) \n\n"+
						"*  If one player chooses paper and the other player chooses rock, then paper\n"+ 
						   "wins. (Paper wraps  rock.)\n\n"+
						"*  If both players make the same choice, the game must be played again to\n"+ 
						   "determine the winner.");
	}
 
	public static int computersTurn(int CT)
	{
 
	Random randomNumbers = new Random();
	CT = randomNumbers.nextInt(3);
	return CT;
	}
 
	public static String usersTurn(String user)
	{
 
	user = JOptionPane.showInputDialog("What is your choice?  ");
	return user;
 
	public static void displayResults(String user, int CT)
	{
	JOptionPane.showMessageDialog(null,"You have" + user + "and the computer has" + CT + "\n");
 
	if (user == "R" && CT == 2)
	{
	JOptionPane.showMessageDialog(null,"You Win! Rock  smashes Scissors.");
	}
	else
		if (user == "S" && CT == 0)
		{
		JOptionPane.showMessageDialog(null,"You Lose! Rock  smashes Scissors.");
		}
		else
			if (user == "P" && CT == 0)
			{
			JOptionPane.showMessageDialog(null,"You Win! Paper wraps  rock.");
			}
			else
				if (user == "R" && CT == 1)
				{
				JOptionPane.showMessageDialog(null,"You Lose! Paper wraps  rock.");
				}
				else
					if (user == "S" && CT == 1)
					{
					JOptionPane.showMessageDialog(null,"You Win! Scissors cuts  paper.");
					}
					else
						if (user == "P" && CT == 2)
						{
						JOptionPane.showMessageDialog(null,"You Lose! Scissors cuts  paper.");
						}
						else
						{
						JOptionPane.showMessageDialog(null,"It's a tie. Play again to beat the tie");
						}
	}
}

As mentioned in other post to a user doing something similar. The issue is you are attempting to compare a String value which is not a primitive variable with ==. When you check for == on an Object it checks the memory reference to see if that matches. You must use String.equals("String to compare")

Duplicate topic.

Please don't start a new topic for the same problem. Continue to work the problem in the original where I believe someone has already offered an answer to this post.
