binding.setVariable("name","John");Stringscript="println 'Hello, ' + name"; shell.evaluate(script);// 输出:Hello, John} } 在这个例子中,我们创建了一个Binding实例,并将其传递给GroovyShell的构造函数。然后,我们使用setVariable方法在Binding中设置变量name的值。在Groovy脚本中,我们可以通过变量name来访...

for in循环 for in 循环语句语法: for(variable in range) { statement #1 statement #2 ... } 1. 2. 3. 4. 5. for in 循环类似java的增强for循环,in 后面可以接数组,集合,map的可以迭代的数据;当然也可以接groovy特有的范围。 跳出循环的关键字有break,continue,return。
PS D:\groovy_example> groovy variable.groovy number is 1, string is Hello, list is [1, 2, 3, 4, 5], map is [one:1, two:2, three:3] 从这个例子,我们可以看出Groovy的另一些特点:一是Groovy与动态语言一样,可以用def关键字来定义变量,而不需要写明具体的类型(实际上def关键字也可以省略);...
offers?Groovy has added new methods compare to old version like •Various array types and object streams with newly Groovy oriented methods like Object.every(), Object.each() etc. and also include new features like “String BufferedReader.getText()” and “InputStream.eachLine(Closure)”.
