  public String Woker(String name){
      this.name = name;
    }
public String setName(String name){
      this.name = name;
    }
public void getName(){
       this.name = name;
    }
}


public class MyClass{
main(){
//The common way
//This object can be invoked repeatedly
Woker xw = new Woker();
buildHouse(xw);

//The anonymous object
//This object can only be invoked here
buildHouse(new Worker(name:"zhangsan"));    

//The anonymouse class
buildHouse(new Woker(name:"MiniWoker"){
// The implement of anonymous class.
//It will display "MiniWoker starts to work"
})

  }

public static void buildHouse(Worker a){
      System.out.println(a.getName() + " starts to work");
    }
