Question

I am trying to write this method, which keeps reading from the user, until the word “exit” is inputted. I tried with a break and for loop; it didn’t work. I was trying with while, but it does not stop even when the word “exit” is inputted. Any ideas how to fix this? Thanks.

public void read(Scanner scanner){

while(3<4){
String in = scanner.nextLine();
Scanner scanner_2 = new Scanner(in);

String name = null;

if(scanner_2.hasNext()){
  //create and add the user to the user container class
  name = scanner_2.next();
  System.out.println(name);
}

if(name == exit)
//stop or break the while loop
}
}

Answer 1

name == exit is wrong.

You want

name.equals(exit)

or

name.equals("exit")

depending on whether exit is a variable or a string literal, respectively. In Java, == means reference equality (e.g Are these two references pointing to the same address in memory), whereas .equals means object equivalence, which is typically overriden in the class by the developer.
