blog__9296215
java.util.Date是在除了SQL语句的情况下面使用的。java.sql.Date是针对SQL语句使用的，它只包含日期而没有时间部分它们都有getTime方法返回毫秒数，自然就可以直接构建。 java.util.Date 是 java.sql.Date 的父类，前者是常用的表示时间的类，我们通常格式化或者得到当前时间都是用他，后者之后在读写数据库的时候用他，因为PreparedStament的setDate()的第2参数和ResultSet的getDate()方法的第2个参数都是java.sql.Date。 java.sql.Date转为java.util.Datejava.sql.Date date=new java.sql.Date();java.util.Date d=new java.util.Date (date.getTime()); java.util.Date转为java.sql.Datejava.util.Date utilDate=new Date();java.sql.Date sqlDate=new java.sql.Date(utilDate.getTime()); java.util.Date utilDate=new Date();java.sql.Date sqlDate=new java.sql.Date(utilDate.getTime());java.sql.Time sTime=new java.sql.Time(utilDate.getTime());java.sql.Timestamp stp=new java.sql.Timestamp(utilDate.getTime());这里所有时间日期都可以被SimpleDateFormat格式化format()SimpleDateFormat f=new SimpleDateFormat(&yyyy-MM-dd hh:mm:ss&);f.format(stp);f.format(sTime);f.format(sqlDate);f.format(utilDate)java.sql.Date sqlDate=java.sql.Date.valueOf(& &);utilDate=new java.util.Date(sqlDate.getTime()); 另类取得年月日的方法：import java.text.SimpleDateFormat;import java.util.*;java.util.Date date = new java.util.Date();//如果希望得到YYYYMMDD的格式SimpleDateFormatsy1=new SimpleDateFormat(&yyyyMMDD&);String dateFormat=sy1.format(date);//如果希望分开得到年，月，日SimpleDateFormatsy=new SimpleDateFormat(&yyyy&);SimpleDateFormat sm=new SimpleDateFormat(&MM&);SimpleDateFormat sd=new SimpleDateFormat(&dd&);String syear=sy.format(date);String smon=sm.format(date);String sday=sd.format(date);}
