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：

外部类通过参数$outer传到内部类里
