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

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

In this article you will be covered: Using Clibuilder for support of command-line options, the parameters required for script execution are passed through command-line options. Use Groovyclassloader to load Groovy class. Use Antbuilder to build the Jar package. Before you begin about this articleMaybe you've written some interesting or useful Groovy scripts and want to share them with

Groovy classes are compiled into bytecode of Java, that is, there is a one-to-one ing between groovy classes and Java classes. Every groovy class can be stored in JavaCodeBecause the groovy class is also a Java class. Usage of groovy list: Def list = [1, 2, 'Hello', n

This article is used to describe some of the groovy-style code in the handling of strings, and the groovy-style code here is mostly different from the coding style of the Java language. First, we're going to define a string object to use as our example: def str = "hello" Now, what we're going to say is the style of the substring. In the Java language, to remove a substring labeled 1 and 2, you must use

There are four ways to annotate groovy, and here's a more detailed look: 1.1 Single-line comment In groovy, single-line comments start with//and can start anywhere in a row, with the following characters being the annotations section. For example: A standalone single line commentprintln "Hello World"//A comment till the end of ofthe line 1.2 Multi-line comments A multiline comment starts with/* and ends w

Groovy tip 10 simplified string operations in groovyIn groovy, operations on string objects are as convenient as operations on List objects. For example, in Java, the substring method is used for operations on string objects. As follows: String STR = "abcdefg"; system. Out. Println (Str. substring (); the result is: BC has two inconveniences: first, the complexity of the substring method and parameters; sec

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.

 This tutorial is written for the latest version of Groovy The same points of groovy and Java are: 0+, 3+, 4+, 6+, 8+, 10+, 12+, 13, 14, 15, 18+, 19+, 20+, 21, 22, 23, 28+, 29+, 30+, 31+, 32+ + indicates that groovy not only covers the Java syntax, but also enhances the The different points of groovy and Java are

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

This article is written for groovy and grails new people, and if you're already familiar with it, please stop, lest you delay your time, and if you have leisure, please criticize this article and correct me. 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

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 critical to the long-term viability of the platform because the life of the computer programming language is usually very short. Since 2008

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
