import java.util.*;
import java.text.SimpleDateFormat;
public class Test {
public static void main(String[] args) {
Date date = new Date();//获取当前日期
SimpleDateFormat df = new SimpleDateFormat("yyyy-MMM-dd kk:mm:ss a");
System.out.println(df.format(date));//按yyyy-MMM-dd kk:mm:ss a这个格式来格式化date
SimpleDateFormat df1 = new SimpleDateFormat(
"yyyyy.MMMMM.dd GGG hh:mm aaa");
System.out.println(df1.format(date));//按yyyyy.MMMMM.dd GGG hh:mm aaa这个格式来格式化date,格式参见下表
}
}
result is:
2014-五月-29 11:34:14 上午
02014.五月.29 公元 11:34 上午
后记:有关yyyy-MMM-dd kk:mm:ss a是什么意思,可以参考SimpleDateFormat的api文档:k: Hour in day (1-24)
