用IDEA建立maven專案後，在main中新建scala目錄，File->Project Structure->Modules設定scala目錄為sources，

再在Libraries中新增Scala SDK。

在scla中新建com.victor.scala包，新建Implict.scala

package com.victor.scala

class Implict {

}

class Test{

}

class RunTest(test: Test){
  def run: Unit ={
    println("RunTest-->test="+test)
  }
}


object Implict extends App{
  //隱式轉換
  implicit def test2RunTest(test: Test) = new RunTest(test)
  val test = new Test
  test.run

  //隱式引數
  def testParam(implicit name:String): Unit ={
    println("name="+name)
  }

  implicit val name ="Implicted......."
  testParam
  //明顯的指明引數
  testParam("test wu ye .....")

  //隱式類
  implicit class ADD(x:Int){
    def add(a:Int):Int = a+x
  }

  println("2.add(23)="+2.add(23))
  //the same to next line
  println("2.add(23)="+ADD(2).add(23))

}

結果：

後續繼續更新。
