樓主能描述清楚一點嗎？是輸入一個日期，計算出這是第幾周？本周還剩余多少天？

public static void main(String[] args) {

int day_count = 3;//總天數(shù)

int week_count = 0;//周數(shù)

int days = 0;//剩余天數(shù)

week_count = day_count / 7;

days = day_count % 7;

System.out.println("周數(shù)" + week_count);

System.out.println("剩余天數(shù)" + days);

}
