ConcurrentHashMapmap = new ConcurrentHashMap<>(); //adding elements to the map map.put("apple", 35); map.put("banana", 20); map.put("orange", 15); //reading elements from the map Integer value1 = map.get("apple"); Integer value2 = map.get("banana"); Integer value3 = map.get("grape");
ConcurrentHashMapIn summary, ConcurrentHashMap is a useful class in the java.util.concurrent package library for handling concurrent access to a Map in Java. It provides thread-safety and efficient performance for concurrent operations on a map.map = new ConcurrentHashMap<>(); //adding elements to the map map.put("apple", 35); map.put("banana", 20); map.put("orange", 15); //removing elements from the map Integer value1 = map.remove("apple"); Integer value2 = map.remove("grape");
