1. Scala 減少傳統傳參的複雜性，在第一句Class語句簡單明瞭的就宣告完畢

Scala: 

   1: class Person(name:String,gender:String) {

   2:  

   3:   def Name=name

   4:   def Gender=gender

   5:  

   6: }

   1: class Employee(name:String,gender:String,skill:String) extends Person(name,gender){

   2:  

   3:     def Skill=skill

   4:  

   5: }

   1: object MyApp extends App

   2: {

   3:   //匿名子類=>定義一個匿名方法 ,在宣告Employee時建立greeting

   4: val employee=new Employee("Benson","Male","Eat"){def greeting="abksjks;j"}

   5:  

   6:  //檢查基類是否為Person

   7:   println(employee.isInstanceOf[Person])

   8:   

   9:   //Wow...這方法居然可以調用

  10:   println(employee.greeting)

  11:   

  12:   println(employee.Name)  

  13:   println(employee.Gender)

  14:   println(employee.Skill)

  15:  

  16: }

Result:
