public class ControlFlow {
 public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    System.out.println("Are you hungry?\n");
    String answer = input.nextLine();
    input.close();
    if(answer == "yes") {
        System.out.println("Food is on the table!");
    }else {
        System.out.println("Not hungry!\n");
     }
  }
}
I tried with boolean variable too. It did not help
