No, it will not be evaluated. And this is very useful. For example, if you need to test whether a String is not null or empty, you can write:
if (str != null && !str.isEmpty()) {
doSomethingWith(str.charAt(0));
}
or, the other way around
if (str == null || str.isEmpty()) {
complainAboutUnusableString();
} else {
doSomethingWith(str.charAt(0));
}
If we didn’t have ‘short-circuits’ in Java, we’d receive a lot of NullPointerExceptions in the above lines of code.
