    Default Wasn't this supposed to work?

    public class test {

    public static void main(String[] args) {
    int x=1000;

    if (Integer.toString(x).length.equals(4) )
    System.out.println("Hi");

    }
    }

    How come this doesn't work?

    1.) 'length' is a function call on the String object, so it needs parenthesis.

    2.) The String 'length' function returns a primitive int, not an object, so you'll need to use '==' instead of 'equals()'.

    3.) Please be sure and use code tags to get highlighting and preserve formatting:

    [C0DE]
    **YOUR CODE GOES HERE**
    [/C0DE]

    (Use O, not zero).

    Hope that helps!

    If you want to compare String, .equals() is the choice.
    If you are comparing int, use == instead.
    Whatever you are, be a good one
