Java Optional.isPresent() is a method in the Java Optional class that checks if a value is present within the Optional. It returns true if the Optional contains a value and false if it is empty. Introduced in Java 2014 with Java 8, isPresent() is commonly used to avoid NullPointerException and handle the presence or absence of values in a cleaner, more functional programming style.
