Why no () needed on args.length == 0

Isn't .length is a method? Therefore it should have been .length() instead of .length ?

if (args.length == 0) { \\ Why is it args.length and not args.length() System.out.println("Usage: java Hangman <answer>"); System.err.println("Answer is required"); System.exit(1); }

Hi, Wan.

In Java, length is a property on the Array Type. Properties cannot be called by using the '()' syntax in Java.
