Groovy is a JVM-based Agile development language that combines many of the powerful features of Python, Ruby, and Smalltalk. first, what is groovy?
In short, Groovy is the next generation of the Java language, and, like Java, it runs in the JVM. As another language running in the JVM, groovy syntax is similar to the Ja

As mentioned above, groovy supports scripts and classes. The previous section briefly describes the relationship between scripts and classes. This section mainly introduces the knowledge of classes in groovy, that is, object-oriented knowledge.1. Type 1.1 Original Ty

Three-day Dragon Boat Festival holiday, I learned jruby and groovy. At last I thought groovy was easy to use. Using groovy is a bit like writing basic, and there are no more rules like Java. During development, code is used to describe the execution logic, rather than writing a large number of classes that comply with Java "patterns" to implement certain logic fu

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 the core of Java development, JDK is the part that all Java programmers need to learn and us
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 Java classes and packages in groovy code, or for performance reasons, we have to
in Jenkins into two categories: the user can log in and the non-logged-in user.1, only if the change of repository, that is, the build has affected the user, will be recorded by Jenkins in the local database. This type of user we are able to browse in the Jenkins interface and view users.But such users are not official Jenki

Let's look at an example of a Java regular expression.Import Java.util.regex.matcher;import Java.util.regex.pattern;public class Testmatch {public static void main ( String[] (args) { pattern pattern = pattern.compile ("g.*"); Matcher Matcher = Pattern.matcher ("Groovy"); System.out.println (Matcher.matches ());} }In fact, this code means that groovy is not a match for regular
Introduction: Groovy's concise syntax frees developers from the typical Java™ architecture that requires code compilation but does not help express what the program really wants to achieve. In this revival of the Groovy series, groovy developer and special columnist J. Scott Hickey takes you through a series of comparisons between regular Java code and Groovy Cod
