有关方法重载的实例（例4-10）

public class Example4_10{
 public static void main(String[] args){
  people zhang=new people();
   System.out.printf("面积："+zhang.getArea(10,8.88));
   System.out.printf("面积: "+zhang.getArea(2.90,10));
  }
 }
 class people{
  double getArea(int x,double y){
  return x*y;
  }
  int getArea(double x,int y){
   return (int)x*y;
   }
 }
