I just started programming with java and I have started to make a text-based game, Here is the code:
The problem is every time I run it and type either ‘left’ or ‘right’ it prints out “Unknown Command”

import javax.swing.JOptionPane;


public class netProject1 {
	public static void main(String[] args) {
		String userInput = JOptionPane.showInputDialog("What's your name?");
		System.out.println("Hello " + userInput + "!");
		System.out.println("");
		System.out.println("Let's Play!");
		String userInput1 = JOptionPane.showInputDialog("Do you go left or right?");

		String room = "";
		
        if (userInput1 == "left") {
            room = ("Kitchen");
    		System.out.println("You are in the "+room);	
        } else if (userInput1 == "right") {
            room = ("Living Room");
    		System.out.println("You are in the "+room);	
        } else {
            System.out.println("Unknown Command");
        }	
	}
}
