nextLine() in java cannot get the exactly value I want

Question

public static void main(String args[]){
    System.out.print("Type new, wil display TRUE:");
    Scanner sc = new Scanner(System.in);
    String userInput = sc.nextLine();

    if(userInput=="new"){
        System.out.println("TRUE");
    }else {
        System.out.println("FALSE");
    }
}

I have no idea why new not equals to new.

Please give me some hints :)

== compares memory allocation position, whereas String.equals(anotherString) compares memory stored value. — Fernando Martín Besteiro, Oct 20 '15 at 18:25

Use userInput.equals("new") instead.

This explains everything: How do I compare strings in Java?
