十二次作业

题目：利用Calendar类计算自己的出生日期距今天多少天，再将自己的出生日期利用SimpleDateFormat类设定的格式输出显示。

package nkk;
import java.util.*;
import java.text.*;
public class text {
    public static void main(String[] args) {
        Scanner r = new Scanner(System.in);
        int y= r.nextInt();
        int m = r.nextInt();
        int d = r.nextInt();
        System.out.println(y+"年"+m+"月"+d+"日"+"出生日期");
        Calendar Now = Calendar.getInstance();//获取当天日期
        
        Calendar riqi = Calendar.getInstance();//获取生日日期
        riqi.set(y, m-1, d);          //获取生日日期
        long time = riqi.getTimeInMillis();   
        long time1 = Now.getTimeInMillis();    
        long days_Mill = (time1-time)/(1000*60*60*24);
        Long days = Long.valueOf(String.valueOf(days_Mill));
        
        System.out.println("一共多少天："+days+"天");
        SimpleDateFormat duo = new SimpleDateFormat("出生日期：yyyy年MM月dd日");
        System.out.println(duo.format(riqi.getTime()));
    

    }

}
