Java Optional.isEmpty() is a method in the Java Optional class that checks whether the Optional is empty (i.e., contains no value). It returns true if the Optional is empty and false if it contains a value. Introduced in Java 2014 with Java 8, isEmpty() is a convenient way to check for the absence of a value in functional programming, providing an alternative to explicit null checks.
