a) What are the benefits of using collections from the

java.util.concurrent package? (b) Describe the

java.util.concurrent.SynchronousQueue in Java? Compare

it to the java.util.concurrent.Exchanger class.

Please site sources

Solution

NOTE : Always prefer to use oracle documentation for

analysing classes ,interfaces,methods and constructors

especially while doing programming in java

Oracle documentation contains complete information

related to

packages,methods,classes,interfaces,constructors

java.util.concurrent package:

java.util.concurrent package in introduced in java 5 . This

package contains a set of classes and interfaces that

makes it easier to develop multithreaded applications in

Java.

Some of the interfaces are

BlockingDeque<E>

BlockingQueue<E>

Callable<V>

CompletionService<V>

ConcurrentMap<K,V>

Some of the classes are

AbstractExecutorService

ArrayBlockingQueue<E>

CopyOnWriteArraySet<E>

Exchanger<V> A synchronization point at which threads

can pair and swap elements within pairs

SynchronousQueue<E> A blocking queue in which each

insert operation must wait for a corresponding remove

operation by another thread, and vice versa.

Both java.util.concurrent.Exchanger class and

java.util.concurrent.SynchronousQueue are the classes in

java

java.util.concurrent.SynchronousQueue

java.util.concurrent.Exchanger class

It contains only two constructors SynchronousQueue()

SynchronousQueue(boolean fair)

It contains only one constructor

Exchanger()

Creates a new Exchanger.

It contains many methods some of the methods are

contains(Object o) Always returns it it contains true or

false if it doesnot contains objects.

containsAll(Collection<?> c)
