JVM-based two languages in the Java environment: Scala,groovyThe two languages can be mixed in a Java project;Scala: Static language, multi-paradigm language, combines object-oriented, process-oriented, and can interoperate with Java and NET, integrating a wide range of language features, including similar net-like closures, lambda expressions, it is more language features, language complexity is also high ~ ~Groovy: Dynamic language, both as an objec
1. Eachline--open and read each line of the fileNew File ("Foo.txt"). Eachline { println it.touppercase ();}2. ReadLines-The function is basically the same as the eachline, but it does not accept the closure as a parameter, but instead reads the file line into a listNew File ("Foo.txt"). ReadLines (); Linelist.each { println it.touppercase ();}3. Spliteachline-Reads each line of the file and then splits the array into rows with the specified delimiter. Needless to say, this method is quite
The collection in groovy is also much simpler to use than Java, and it's nice to note that groovy also offers many handy ways to sort the numbers in a collection, to find the maximum or minimum value, to reverse the elements, to overlap, to remove duplicate elements, to merge the arrays, to select the features that fit the criteria, Because these methods intellij the IDE with code hints, they are not explai
Exploration of groovy-covering invokemethod during the runtime of MOP 11
We will have been using the groovy hook language for a long time, that is, the "invokemethod" method and several other methods. We will implement the "invokemethod" method in a class, which is used to assign all or part of the methods of the class instance called during the runtime. We have discussed these in detail in the mop invok
Groovy's team leader--Guillaume Laforge says that MOP (Meta Object Protocol) is his favorite groovy feature.
Using mop can simply intercept and interpret properties and methods, and intercept has become familiar with AOP. In groovy, by overloading the Groovyobject Get/setproperty () function and the InvokeMethod () function, you can add your own hooks and behavior, More simple than Java to implement proxy a

Groovy supports two types of strings: A generic Java string, an instance of java.lang.String, and Gstrings, which is an instance of groovy.lang.GString, and allows the text to contain placeholders. Gstrings is not a subclass of string because the string class is the final class (final Class) that cannot be inherited. However, Gstring is the same as a generic string, because groovy can transform gstrings int
Scott Davis will continue the discussion of Groovy metaprogramming, and this time he will delve into @Delegate annotations, @Delegate annotations blur the distinction between data types and behavior and static and dynamic types.
In the past few sessions of groovy, you've learned how groovy language features such as closures and metaprogramming add dynamic functi
This will be a series of text that expands our approach to the use of custom range classes. Perhaps we unknowingly use the range class in the groovy language, not even aware of it, or we often marvel at the convenience of using the range class in the coding process of the groovy language, but just marvel that we're not paying for it. Or we want to use the custom range class in the actual encoding, but we ca
each sub-project individually. This effect can be achieved by subprojects tasks. However, some of the custom settings for project need to be configured separately. For example, the following code
set the encoding for each sub-item
Build.gradle
subprojects {
Sonar {
Project {
sourceencoding = ' UTF-8 '
}
}
}
If you want to set up a specific subproject, you can set it in the project task in Gradle, in the form project (' Subproject name '),
It is now more popular to use Gradle to configure projects, and this article focuses on studio and IntelliJ packaging. In an Android Gradle project, project is similar to Eclipse's workspace, and Moudule is similar to project for Eclipse.

Assertions are used to verify that a hypothetical condition is true, and in groovy's assertion, if the hypothetical condition is not true, a Java.lang.AssertionError exception is thrown. Use the groovy expression to test the hypothetical condition.Such asassert 1==2: "One isn ' t"Will throw an exception:Exception thrownjava.lang.AssertionError:One isn' t.

Introduction: Online social networking is now very popular. In this article you'll learn how to mix Google maps, Twitter, Groovy, and Ajax to build social networks. By combining Google maps with location information that Twitter exposes, you can create a mashup (mashups) application that allows people to view Twitter in a specific location. The simple application built in this article allows users to view a map of their friends on Twitter-a network ge
The definition of an array and the initial value of an assignment
In the groovy language, arrays are defined in the same way as in the Java language.
def a = new String[4] def nums = newint[10] def objs = new Object[3]
And then the assignment is the same:
a[0] = 'a' a[1] = 'b' a[2] = 'c' a[3] = 'd'
The difference is in assigning an initial value when the array is defined.
In the Java language, this is defined as an array of strings:
