看个Scala的例子：

package method

/**

* @author I042416

*/

class booleaMethod {

 private var firstName = ""

 private var lastName = ""

 def this(first: String, last: String) { // this is an Auxiliary constructor

      this() // call primary constructor

      this.firstName = first

      this.lastName = last

 }

 

 def printArgs(args: Array[String]): Integer = {

     args.foreach(println)

     return args.length

    }

 

 def getName( bGetfullName: Boolean): String = {

     if( bGetfullName) {

       this.firstName + " " + this.lastName

     }

     else{

       this.firstName

     }

 }

}

object testBoolean extends App {

 val booleanMethod = new booleaMethod("Jerry", "Wang")

 println(booleanMethod.getName(bGetfullName = false))

 println(booleanMethod.getName(bGetfullName = true))

 

}

产生一个内部类：
