groovy for java developers

It has been said before that many people choose groovy because of their low learning costs, as long as you have the basics of Java and learn quite quickly. In contrast, Scala (another JVM dynamic language) syntax is more difficult to learn (though not yet learned, but online reviews are).As a Java programmer, I'm going to get myself groovy.From JDK to GDK1. As th

Since the groovy language is an extension of the Java language, it's hard to get involved with the Java language when we're using the groovy language, so we're doing a pure groovy language project like a grails project. We might use legacy

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

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

In a keynote speech with Martin Fowler, he provided a keen observation report: The legacy of Java is the platform , not the language . The original Java technical engineer had made a great decision to separate the language from the runtime, eventually enabling more than 200 languages to run on the Java platform . This infrastructure is crit

Scala"", "Sans-serif" '> and groovy are both JVM-based languages, which have more concise syntax and rich expression capabilities than Java. Scala and groovy are good choices for developers who want to avoid tedious Java statements without leaving the JVM. But which one can

What is a byte code?Bytecode can also be said to be a language, or an operational primitive that communicates with the operating system. The purpose of bytecode is actually to shield operating system differences, operating system differences to the professional virtual machine developers, they want to ensure that their development of virtual machines compatible with a variety of hardware platforms.Why the groovy
