Java AbstractMap.put() is a method in the Java AbstractMap class that associates a specified key with a value in the map. If the key is already present, it updates the value associated with the key. Introduced in Java 1997 with Java 1.2, put() is essential for adding or updating key-value pairs in Java's Map collections, such as Java HashMap or Java TreeMap.
