Making Java Groovy

Summary

Making Java Groovy is a realistic instruction manual for builders who are looking to mixture Groovy into their day by day paintings with Java. It begins via introducing the major alterations among Java and Groovy—and how one can use them in your virtue. Then, it courses you step by step via reasonable improvement demanding situations, from net functions to internet prone to machine functions, and indicates how Groovy makes them more uncomplicated to place into production.

About this Book

You don't want the total strength of Java whilst you're writing a construct script, an easy approach software, or a light-weight internet app—but that's the place Groovy shines brightest. This dependent JVM-based dynamic language extends and simplifies Java so that you can be aware of the duty handy rather than handling minute information and pointless complexity.

Making Java Groov is a pragmatic advisor for builders who are looking to reap the benefits of Groovy of their paintings with Java. It starts off by means of introducing the major transformations among Java and Groovy and the way to take advantage of them for your virtue. Then, you'll concentrate on the occasions you face on a daily basis, like eating and growing RESTful internet providers, operating with databases, and utilizing the Spring framework. You'll additionally discover the good Groovy instruments for construct approaches, trying out, and deployment and how you can write Groovy-based domain-specific languages that simplify Java development.

Written for builders accustomed to Java. No Groovy event required.

Sample text

To learn this concept, we will implement an example with two threads accessing a common object. We will have a bank account and two threads; one that transfers money to the account and another one that withdraws money from the account. Without synchronization methods, we could have incorrect results. Synchronization mechanisms ensures that the final balance of the account will be correct. Getting ready The example of this recipe has been implemented using the Eclipse IDE. If you use Eclipse or other IDE such as NetBeans, open it and create a new Java project.

Now, add the synchronize keyword as you learned before and run the program again. As you can see in the following screenshot, now you obtain the expected result. If you run the program often, you will obtain the same result. Refer to the following screenshot: 50 Chapter 2 Using the synchronized keyword, we guarantee correct access to shared data in concurrent applications. As we mentioned in the introduction of this recipe, only a thread can access the methods of an object that use the synchronized keyword in their declaration.

When it detects that it has been interrupted, it throws an InterruptedException exception and continues the execution in the run() method, no matter how many recursive calls have been made. There's more... The InterruptedException exception is thrown by some Java methods related with the concurrency API such as sleep(). 18 Chapter 1 See also ff The Interrupting a thread recipe in Chapter 1, Thread Management Sleeping and resuming a thread Sometimes, you'll be interested in interrupting the execution of Thread during a determined period of time.
