In an if statement, can a String be a condition? [duplicate]

guys. I am trying to print a double if a String from a user says a certain word. Here is the code:

package everything;
import java.util.*;

public class Replit {
    public static void main(String[] args) {

        Scanner s = new Scanner(System.in);
        String in = s.next();

        //your code here
        if(in=="burger" || in == "chicken"){
            double bc = 10.0;
            System.out.println(bc);
        }else if(in == "soda"){
            double soda = 2.0;
            System.out.println(soda);
        }else if(in == "fries"){
            double fries = 3.5;
            System.out.println(fries);
        }
        s.close();
    }
}
