代碼如下：
package test41
//泛型特質
object test3 {
//定義一個日志//泛型特質，X是泛型名稱，可以更改。trait Logger[X] {val content: Xdef show():Unit
}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()}
}

運行結果如圖：
