Java HashMap.remove() is a method in the Java HashMap class that removes the entry for the specified key from the map. It takes the key as an argument and returns the value associated with the key, or null if the key does not exist. remove() is commonly used in applications that require dynamic modification of collections. Introduced in Java 1995 with Java 1.2, remove() is a key method for managing key-value pairs in a Java HashMap.
