Groovy language is most proud of the characteristics of the DSL, the definition of DSL and classification, advantages, etc., it is not to be elaborated in this article, you can access the Internet, there is a large number of this convenient introduction. The groovy language is a great way to design your internal DSL, and in this context, my Groovy Discovery serie
1. In Groovy, def can be used to define non-type variables (which is similar to var in JavaScript in defining variables), and return a non-type method without def in Java.
2. The equals method in Java corresponds to = in Groovy, And the = (to determine whether to reference the same object) in Java corresponds to the is method in Groovy.
3. Define the array in Jav
What is groovy?
Groovy is an alternative language for JVM-SubstitutionJava programming on the Java platform using groovy is basically the same as using Java code. Note: it does not mean that groovy replaces Java, but that groovy and Java are well integrated for programming.

When a Java developer joins groovy's development trip, he/she often takes Java thinking and learns about groovy, learning one feature at a time, which allows him to slowly become more creative and write groovy code that is more in line with language habits. The purpose of this article is to guide these developers to learn basic groovy programming styles, learn ne
There are two ways to run the groovy class in JVM:
Compile all *. Groovy Java *. class files using yyc, put these *. class files in the Java class path, and load these classes through the Java class loader.
Use the groovy class loader to directly load at runtime *. groovy file and generate objects. In this way, no * is
JVM is awesome!
Developers people that Bash Java make the mistake of mixing up the Java language and the Java platform. sure, the Java language is verbose; it lacks closures, mixins, etc. but the JVM is freaking awesome. it's blazing fast, it runs everywhere, has multiple garbageCollectors, has native threads and great monitoring tools. as a result, you may still want to run your server-side applications on the JVM. the best part is that you don't have to use the Java language. if you are a fan

Groovy, a dynamic language that runs on the JVM, has syntax similar to Java syntax, is much loved by Java programmers, and supports Java syntax directly. Grails, a rails style framework based on
Groovy, the Java Dynamic language for the JVM, is as ripe as a vintage wine. Following the successful release of Groovy 1.0 in January 2007, the next major milestone, version 1.5, has been released. There are some interesting and novel places in version 1.5, and we'll look at these features in this article. Language primarily enhances support for Java 5 features, including annotations, generics, and enumera
Java will be a platform rather than a programming language.
The original engineers of Java made a wise decision to separate the programming language from the runtime environment, which eventually allowed over 200 languages to run on the Java platform. This architecture is crucial to the long-term vitality of the platform, because the computer programming language generally has a short life cycle. The annual JVM language summit, sponsored by Oracle, started in 2008, provided an opportunity for op
This is caused by an online problem:Background:The groovy engine embedded in the app dynamically executes the incoming expression and returns the result of the executionOnline questions:
The discovery of the FULLGC of the machine began to skyrocket at some point and continued;

I am a work Flow project, the workflow of each template engine needs to execute a dynamic business, these dynamic business has a variety of implementations, the most common is the user to write a script file, and then the workflow engine executes here, run the script file.This function of running the script file was originally implemented with Scriptenginemanager. Ask the user to provide a jar to implement the business, and write a JS script, the script dynamically call Java built into the JS en
Frankly speaking, I have never been so optimistic about this scripting language. The reason may be that they are not so eager for new technology now. But I have found that this is not a good idea. So I finally decided to use groovy to see what the wind was doing to make it look good.Of course, I do not know the language very well, so there may be a bias in my discourse. Also hope Haihan.
