class ApplyTest {

  def apply() = "Apply customer"



  def test(): Unit = {

    println("test")

  }

}



object ApplyTest{

  def apply() = new ApplyTest



  def static: Unit ={

    println("i'm a static method")

  }

}





object Apply {

  def main(args: Array[String]) {

    val app = ApplyTest()  //这里使用的是object AppyTest  ， 因为apply中实例化了class AppleTest，所以才能调用test

    app.test



    val app1 = new ApplyTest  //这里实例化的是class ApplyTest

    app1.test



    println(app())

    println(app1())

  }

}
