How to make a while loop end with a specific input

Question

This is the code I have right now and can't figure out why this while loop isnt ending when there is a period entered.

while (emailTxt!="."){
  emailTxt = "";
  emailTxt = scanner.nextLine();
  totalText.add(emailTxt);
}

You should use emailTxt.equals() or emailTxt.contains() to do comparison. — HarryQ, Sep 22 '20 at 20:30
You should have used `!".".equals(emailTxt)` instead of `!=` operator — Nowhere Man, Sep 22 '20 at 20:30

emailTxt is a String. A String in Java is considered an Object. You want to use the Object.equals().

So

while(!(emailTxt.equals("."))

You should use equals() to compare two string.

while (!".".equals(emailTxt)) {
    // ...
}
