java.sql.Date类型时间获取当前时间,精确到时分秒的方法

如题

Answer 1

Date date = new Date();
DateFormat df1 = DateFormat.getDateInstance();//日期格式，精确到日
System.out.println(df1.format(date));
DateFormat df2 = DateFormat.getDateTimeInstance();//可以精确到时分秒
System.out.println(df2.format(date));
DateFormat df3 = DateFormat.getTimeInstance();//只显示出时分秒
System.out.println(df3.format(date));
DateFormat df4 = DateFormat.getDateTimeInstance(DateFormat.FULL,DateFormat.FULL);
System.out.println(df4.format(date));
DateFormat df5 = DateFormat.getDateTimeInstance(DateFormat.LONG,DateFormat.LONG);
System.out.println(df5.format(date));
DateFormat df6 = DateFormat.getDateTimeInstance(DateFormat.SHORT,DateFormat.SHORT); System.out.println(df6.format(date));
DateFormat df7 = DateFormat.getDateTimeInstance(DateFormat.MEDIUM,DateFormat.MEDIUM); System.out.println(df7.format(date));
