10-Groovy-数据类型-Map介绍

// map创建   空的map,用[:]表示
def employee =[
        "name":"大海",
        "age":"28",
        "city":"北京"
]
// 获取map的value
println employee.name
println employee["name"]
println employee.get('age')
println employee.getAt('city')

// 添加元素和大小
def employee1 =[
        "name":"大海",
        "age":"28",
        "city":"北京"
]
// 大小
println employee1.size()
// 添加
employee1.put("tel", "16612345678")
println employee1.size()
println employee1

// 包含判断和克隆
def employee2 =[
        "name":"大海",
        "age":"28",
        "city":"北京"
]
// containsKey 包含的key
println employee2.containsKey('name')
// containsValue 包含的值
println employee2.containsValue('28')
// clone 克隆
def emp2 = employee2.clone()
println emp2

// 遍历 java 方法
def employee3 =[
        "name":"大海",
        "age":"28",
        "city":"北京"
]
def entry = employee3.entrySet()
for (e in entry) {
    println e.getKey() + ":" + e.getValue()
}
