Java Double is a wrapper class for the Java double primitive type, allowing it to be used as an object. Java Double provides useful methods for performing mathematical operations, comparing values, and converting between string representations and double values. Introduced in Java 2004 with Java 5, Double is part of Java's wrapper classes, which allow primitive types to be treated as objects for use in collections and other contexts that require objects.
