Java Optional.map() is a method in the Java Optional class that transforms the value inside the Optional if it is present, applying the provided function. If the Optional is empty, it returns an empty Optional. Introduced in Java 2014 with Java 8, map() is a key method for functional programming in Java, enabling safe transformations and chaining operations on optional values without explicitly checking for null.
