/**

//隐式转换
class Implicit(a: A) {
  def Test: Unit = {
    println("Implicit")
  }
}

class A {

}

object Implicit {
  //隐式转换
  implicit def a2Implicit(a: A) = new Implicit(a)

  def ImplicitMethod(implicit name: String): Unit = {
    println(name)
  }

  //隐式类
  implicit class JiSuan(x: Int) {
    def add(a: Int): Int = a + 1
  }

  def main(args: Array[String]) {
    //隐式转换
    val a = new A
    a.Test

    //隐式参数
    implicit val name = "hark"
    ImplicitMethod
    ImplicitMethod("kxy")

    //隐式类
