scala 继承 父类 子类

一.父类 子类

package dsj03
  //继承
  // class 子类 extends 父类
// 定义：在原有类的基础上定义一个新类 原有类称为父类 新类称为子类 class子类名 extends 父类名(类体)

/**
object class01 {

  //动物
    class Aniaml(){
      def eat():Unit = {
        println("animal eat...")
      }
}

  class Dog() extends Aniaml() {

}

def main(args: Array[String]): Unit = {
  val d1 = new Dog()
  d1.eat()
  }
}
