Scala的泛型类和泛型特质

1.Scala泛型类

object Test5 {//格式//定义:类名[T]//使用:类名[类型]abstract class A[T](){val data : Array[T]}class A1 extends A [Int]{override val data : Array[Int]=Array(1,2,3)}class A2 extends A[String]{override val data=Array("a","b","c")}def main(args: Array[String]): Unit = {val a = new A1()val rs = a.data(1)println(rs)val b = new A2()val rs1 = b.data(1)println(rs1)}
}

2.Scala泛型trait

//泛型trait
//定义格式:trait 特质名[泛型]
//使用格式:特质名[具体的类型]
object Test6 {trait Logger[T]{val name:Tdef show(b:T):Unit ={println(b)}}class A extends Logger[String]{override val name = "test"}def main(args: Array[String]): Unit = {val a1 = new A()a1.show("hi")}
}
