kotlin嵌套类

package loaderman.demo

class Outer {
     var name: String = "name"

    inner  class inner {//inner关键字获取外部类的实例引用
        fun getName(): String = name
    }

    class Ha{
        fun go()=3
    }
}

package loaderman

import loaderman.demo.Outer


fun main(arg: Array<String>) {


    val name = Outer().inner().getName()//注意 Outer()和Outer区别
    val go = Outer.Ha().go()
    println(name)
    println(go)
}
