C++写的一个计算两个日期之间天数的小程序: #include <Windows.h> #include <stdio.h> struct tagDate { int year; int month; int day; }; //设置日期 void SetDate(int y, int m, int d, tagDate *date) { date->year = y; date->month = m; date->day = d; } //是否闰年 int Is
java如何计算两个日期之间相差多少天? public static void main(String [] args) { Date now = new Date(); Calendar cal = Calendar.getInstance(); cal.set(2015,2,24);// cal.set(Calendar.YEAR, 2015);// cal.set(Calendar.MONTH, 2);// cal.set(Calendar.DATE, 24); long interval
oracle如何计算两个日期的相差天数.月数.年数.小时数.分钟数.秒数 1.相差天数(两个日期相减) --Oracle中两个日期相差天数-- select TO_NUMBER(TO_DATE('2018-6-5','yyyy-mm-dd hh24:mi:ss')- TO_DATE('2018-5-31','yyyy-mm-dd hh24:mi:ss')) AS 相差天数 from dual; 2.相差小时数.分钟数.秒数 --Oracle中两个日期相差小时数-- ) AS 相差小时数 from
1--Java 分析:调用java中Calendar类 int days(Date date1,Date date2){ Calendar cal = new Calendar.getInstance(); cal.setTime(date1); int time1 = cal.get(Calendar.DAY_OF_YEAR); cal.setTime(date2); int time2 = cal.get(Calendar.DAY_OF_YEAR); //long days = Math.a
