ConcurrentHashMap class obeys the same functional specification as HashTable and includes all the versions of methods corresponding to each method of a HashTable. A HashTable… Read More
The ConcurrentHashMap and SynchronizedHashMap both are the Collection classes which are thread-safe and can be used in multithreaded and concurrent java application. But there are… Read More
The contains() method of Java.util.ConcurrentHashMap is used to check whether if some key maps into the specified value in this table. It is a legacy… Read More
The values() method of ConcurrentHashMap class in Java is used to create a collection out of the values of the map. It basically returns a… Read More
The keySet() method of ConcurentHashMap class in Java is used to create a set out of the key elements contained in the hash map. It… Read More
The compute(Key, BiFunction) method of ConcurrentHashMap class is used to compute a mapping for the specified key and its current mapped value (or null if… Read More
The keys() method of ConcurrentHashMap class in Java is used to get the enumeration of the keys present in the hashmap. Syntax: Enumeration enu =… Read More
The elements() method of ConcurrentHashMap class in Java is used to get the enumeration of the values present in the table. Syntax: Enumeration enu =… Read More
The computeIfAbsent(Key, Function) method of ConcurrentHashMap class which attempts to compute its value using the given mapping function for specified key if key is not… Read More
The entrySet() method of ConcurrentHashMap in Java is used to create a set from the same elements contained in the concurrent hash map. It basically… Read More
In hashing there is a hash function that maps keys to some values. But these hashing function may lead to collision that is two or… Read More
The java.util.concurrent.ConcurrentHashMap.putIfAbsent() is an in-built function in Java which accepts a key and a value as parameters and maps them if the specified key is… Read More
The java.util.concurrent.ConcurrentHashMap.putAll() is an in-built function in Java which is used for the copy operation. The method copies all of the elements i.e., the mappings,… Read More
The isEmpty() method of java.util.concurrent.ConcurrentHashMap is an in-built function in Java which checks if this map contains any key-value mappings and returns a boolean value.… Read More
The get() method of java.util.concurrent.ConcurrentHashMap is an in-built function in Java which accepts a key as parameter and returns the value mapped to it. It… Read More
