HashMapand HashSet. Java 1.5 included Concurrent implementations; for example ConcurrentHashMap and CopyOnWriteArrayList. Usually Collection classes are not thread-safe and their iterator is fail-fast. In this section, we will learn about commonly used collection classes...
To get started with streams, head over to the Java 8 Stream API Tutorial. To combine arrays using a Stream, we can use this code: Object[] combined = Stream.concat(Arrays.stream(first), Arrays.stream(second)).toArray(); Stream.concat() creates a concatenated stream in which the...
Inverting a Map In Java This Java tutorial will teach us how to invert a given Map using different techniques. We will learn to invert Maps with unique values and create Multimap when there are duplicate values. 1. What is an Inverted Map? An inverted Map <V, K> is an instance of the...
The Java Collections Framework was designed to ensure complete interoperability between the corecollection interfacesand the types that were used to represent collections in the early versions of the Java platform:Vector,Hashtable,array, andEnumeration. In this section, you'll learn how to transform ...
The count goes down whenever a consumer thread calls task_done() to indicate the item was retrieved and all work on it is complete. When the count of unfinished tasks drops to zero, join() unblocks. ''' with self.all_tasks_done: while self.unfinished_tasks: self.all_tasks_done.wait(...
