java代码如何获取当前时间为本月的第几周,本周的第几天呢?

实现思路:
    使用Calendar对象中的指定方法，如
	  //获取当前时间为本月的第几周
	 int week = calendar.get(Calendar.WEEK_OF_MONTH);
	 //获取当前时间为本周的第几天
	 int day = calendar.get(Calendar.DAY_OF_WEEK);

package com.java265;
 
import java.text.SimpleDateFormat;
import java.util.Calendar; 
/** 
 * 注意事项:
 * 在Calendar中每周是从我们中国人的周日(星期七)开始计算的.
 * 所以Calendar的周一实际为我们中国人的上周的星期七
 */
public class TestWeekActivity  {
    @Override
    public void onCreate(Bundle savedInstanceState) {
         
        getCurrentTime();
        getWeekAndDay();
        
    }
    
    
    private void getWeekAndDay(){
    	 Calendar calendar= Calendar.getInstance();
    	//获取当前时间为本月的第几周
    	 int week = calendar.get(Calendar.WEEK_OF_MONTH);
    	 //获取当前时间为本周的第几天
    	 int day = calendar.get(Calendar.DAY_OF_WEEK);
    	 if (day==1) {
			day=7;
			week=week-1;
		} else {
            day=day-1;
		}
    	 System.out.println("今天是本月的第" + week + "周"+",星期"+(day));
 
    }
   
   //获取当前时间(精确到天)且判断季节
	private void getCurrentTime() {
		SimpleDateFormat sDateFormat = new SimpleDateFormat("yyyy-MM-dd");
		String date = sDateFormat.format(new java.util.Date());
		System.out.println("date=" + date);
		String dates[] = date.split("-");
		System.out.println("dates[0]=" + dates[0]);
		System.out.println("dates[1]=" + dates[1]);
		System.out.println("dates[2]=" + dates[2]);
 
		System.out.println("---------------------");
 
		System.out.println("dates[0]=" + Integer.valueOf(dates[0]));
		System.out.println("dates[1]=" + Integer.valueOf(dates[1]));
		System.out.println("dates[2]=" + Integer.valueOf(dates[2]));
 
		int month = Integer.valueOf(dates[1]);
		String season = null;
		if (month == 12 || month == 1 || month == 2) {
            season="冬天";
		} else if(month == 3 || month == 4 || month == 5){
			season="春天";
		} else if(month == 6 || month == 7 || month == 8) {
			season="夏天";
		}else {
			season="秋天";
		}
		
		System.out.println("季节:"+season);
	}
