11-Groovy-Closures(闭包)和Ranges(范围)

// 定义闭包
def myClosure = { println "Hello Groovy" }
// 调用闭包
myClosure.call()

// 带参数的闭包
def myClosure1 = { name -> println "Hello ${name}" }
// 调用闭包
myClosure1.call("大海")

// 带返回值的闭包
def myClosure2 = {
    a, b, c ->
        return (a + b + c)
}
// 调用闭包
println myClosure2(1, 2, 3)

// 遍历List
def myList = ["大海", "28", "测试工程师", "辽宁人"]
myList.each {
    info ->
        println info
}

// 遍历Map
def myMap = [
        "name": "大海",
        "age" : "28",
        "city": "北京"
]
myMap.each {
    key, value ->
        println key + ":" + value
}

// 创建有序序列
def range = 1..10   // 包含10
println range.size()
println range.getFrom()  // 首个值
println range.getTo()  // 最后一个值
println "---------------------"
// <value  不包含value   不包含10
def range1 = 1..<10
println range1.size()
println range1.getFrom()
println range1.getTo()

// 遍历range
def range2 = 1..20
for (i in range2) {
    println(i)
}
