Mastering Concurrency Programming with Java 8

Possible problems in concurrent applications

Programming a concurrent application is not an easy job. If you incorrectly use the synchronization mechanisms, you can have different problems with the tasks in your application. In this section, we describe some of these problems.

Data race

You can have a data race (also named race condition) in your application when you have two or more tasks writing a shared variable outside a critical section—that's to say, without using any synchronization mechanisms.

Under these circumstances, the final result of your application may depend on the order of execution of the tasks. Look at the following example:

package com.packt.java.concurrency; public class Account { private float balance; public void modify (float ...
