Scala的泛型

package test39
//泛型特质

object test5 {
//定义一个日志
  //泛型特质.X是泛型名称，可以更=更改
  trait Logger[X]{
  val content:X
  def show():Unit
}
  //定义一个类去实现特质
  class FileLogger extends Logger[String]{
    override val content: String = "file"
    override def show(): Unit = {
      println(content)
    }
  }

  def main(args: Array[String]): Unit = {
    val fileLogger = new FileLogger()
    fileLogger.show()
  }
}
