Concurrent Stack Assignment

Motivation

We will build a thread-safe implementation of a Stack using synchronized methods.

Background

Implicit Locks

synchronized methods

Code To Implement

ConcurrentStack

To be @ThreadSafe, one must hold intrinsic lock (via synchronized) on the ConcurrentStack instance for each of the methods which read and/or write to mutable data.

class:	ConcurrentStack.java
methods:	constructor push peek pop
package:	stack.concurrent.exercise
source folder:	student/src/main/java

constructor and instance variables

Be sure to initialize whatever state you need to implement a mutable thread-safe Stack.

Testing

class:	__ConcurrentStackTestSuite.java
package:	stack.concurrent.exercise
source folder:	testing/src/test/java
