日期时间显示的多种格式

1、日期时间显示的java类: 文件名：Datetime.java

2、在JSP文件中显示不同的日期时间格式：JSP文件名：datetime.jsp

3、日期时间脚本显示：文件名：time.htm

package net.xiaoxiang.dateTime;

// 日期时间显示的多种格式类：文件名：Datetime.java
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;
