How to split up complex conditions and keep short circuit evaluation?

Question

Sometimes conditions can become quite complex, so for readability I usually split them up and give each component a meaningful name. This defeats short-circuit evaluation ho

Answer 1

This question is from 2009 but in the future (Java 8) we will be able to use Lambda expressions that may be for this context just like boolean expressions but you can use it so they are only evaluated when needed.

public static void main2(String[] args) {

    Callable argsNotNull = () -> args != null;
    Callable argsLengthOk = () -> args.length == 2;
    Callable argsAreNotEqual = () -> !args[0].equals(args[1]);

    if (argsNotNull.call() && argsLengthOk.call() && argsAreNotEqual.call()) {
        System.out.println("Args are ok");
    }
}

You can do the same with java 5/6 but it is less efficient and much more ulgy to write with anonymous classes.
