Why doesn't this read my string please? I keep getting "animal unknown" 😕 thanks

String animal; Scanner scan = new Scanner(System.in); animal = scan.nextLine(); if(animal == "frog"){ System.out.print("Croak!");} if(animal == "dog"){ System.out.println("Woof!");} if(animal == "cow"){ System.out.println("Moo!"); }else{ System.out.println("Animal unknown");}

I think it's because you use ==. If you compare 2 strings you should use .equals or .equalsIgnoreCase and than it should work :)

Do if ( condition 1){ } else if (condition 2){ } else if (condition n){ } else { // what's supposed to happen if it's none of the above } there u go ;)

Why are you concatenating frog,cow and dog? Use and for final condition.
