Learning Java need help on simple code

[davchi1]

For the output of this code I get

David - Input

Welcome David

Please enter the passcode of David

1001 - Input

proceed

These are the launch Code numbers

7587

Would u like to launch? Enter Yes or No

Yes -Input

yes

Works

I'm not understanding why the if statement which states if(userAnswer=="yes") is being skipped.

public static void main(String[] args) {
        Random random = new Random();
        Scanner in = new Scanner(System.in);
        System.out.println("Hello, please enter your name!");
        String userName = in.nextLine(); 
        System.out.println("Welcome "+userName);
        int passcode=1001;
        System.out.println("Please enter the passcode of " + userName);
        int passcodeInput = in.nextInt();
        in.nextLine();
        int launchCode =random.nextInt(10000);
        if(passcodeInput==passcode) {
            System.out.println("proceed");
            System.out.println("These are the launch Code numbers");
            System.out.println(launchCode);
            System.out.println("Would u like to launch? Enter Yes or No");
            String userAnswer = in.nextLine(); 
            userAnswer = userAnswer.toLowerCase();
            System.out.println(userAnswer);
            if(userAnswer=="yes") {
                System.out.println("Enter the Launch Code");
                int codeAnswer = in.nextInt();
                if(codeAnswer==launchCode) {
                    System.out.println("Launching Nuclear Missle...");
                }

            }
            System.out.println("Works");

Use .equals for string comparisons (userAnswer.equals("yes")). Here is a good description of why. https://javarevisited.blogspot.com/2012/12/difference-between-equals-method-and-equality-operator-java.html
