Java if-statement strange things happening [duplicate]

I'm probably missing something really basic but can't understand why despite my input my if-statement just goes directly to my else-statement.

Here is my code:

        for(int i = 0; i<10; i++){
        String input=UserInput.getUserInput();
        if(input == "field"){
            player.moveTo(field);
            }
        if(input == "forest"){
            player.moveTo(forest);
            }
        if(input == "ocean"){
            player.moveTo(ocean);
            }
        if(input == "cave"){
            player.moveTo(cave);
            }
        if(input == "room"){
            player.moveTo(room);
            }
        else{
            System.out.println("Incorrect location!");
        }
        player.getLocation().describeYourself();
    }

And here is my UserInput class:

import java.util.Scanner;


public class UserInput {

public static String getUserInput(){
    Scanner in = new Scanner (System.in);
    String input = in.nextLine();
    return input;
}

}
