mydate.java

这一些程序都是实验之用

public class MyDate extends B{
	private int day,month,year;
	public MyDate(int d,int m,int y){this.day=d;this.month=m;this.year=y;}
	
public boolean equal(Object o){
		boolean result=false ;
		if((o!=null)&&(o instanceof MyDate)){
		  System.out.println("result="+result);  
		  MyDate d=(MyDate)o;
		 	
		 if((day==d.day)&&(month==d.month)&&(year==d.year))
		 {result=true;
		  System.out.println("result="+result);
		  }
		                                    }
		 
	return result;
	}
	public static void main(String args[])
	 {
	 	MyDate one=new MyDate(10,10,2006);
	 	MyDate other=new MyDate(10,10,2006);
	 	B b=new B();
	 	System.out.println(one==other);
	 	System.out.println(one.equal(b));
	 }
	
	}
class B{}
