Question

Why doesn’t my loop end when I enter “Done”?

    List<String> x = new ArrayList<String>();
    BufferedReader is = new BufferedReader(new InputStreamReader(System.in));
    String line = "";

    while (line != "Done")
    {
        System.out.println("?> ");
        line = is.readLine();
        x.add(line);

    }

Answer 1

You have to use equals when comparing strings. Try this:

while(!"Done".equals(line))

!= will check the reference, not the content of the string.
