java Calendar 根据周推算时间
java 中能否通过哪一周确定这周的时间范围？请大虾指教
[解决办法]

import java.text.SimpleDateFormat;
import java.util.Calendar;

public class Aloha {
    public static void main(String[] args) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.WEEK_OF_YEAR, 10);

        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
        System.out.println(formatter.format(calendar.getTime()));
    }
}
