慢慢的，回想起以前学习JAVA和C#当中的的类的特性了。
感觉大同小异吧。。。
package com.hengheng.scala
class OOPInScala {
}
class Student(name: String, age : Int, val major : String) extends Person(name, age) {
println("This is the subclass of Person, major is :" + major)
override def toString = "Overrided toString method....."
override val University = "TsingHua"
}
class Person(val name : String, val age : Int){
println("This is the primary constructor!")
var gender : String = _
def this(name :String, age : Int, gender : String){
this(name, age)
this.gender = gender
}
val University = "BJU"
}
//class Person {
// var name : String = _
//val age = 27
//private[this] val gender = "male"
//}
object OOPInScala{
def main(args: Array[String]) {
val p = new Person("Rocky", 27, "male")
//val p = new Person
//p.name = "Rocky"
println(p.name + ":" + p.age + p.gender)
// println(p.gender)
val s = new Student("Rocky", 27, "Computer")
println(s.toString)
println(s.University)
}
}
输出：
This is the primary constructor!
Rocky:27male
This is the primary constructor!
This is the subclass of Person, major is :Computer
Overrided toString method.....
TsingHua
