一些JavaAPI测试的源代码(包括一些Java中常用的数据结构类

/**　在JDK1.5中java.util.Date
 *	与java.sql.Date都已过时，
 *　应尽量用java.util.Calendar　**/

import java.util.Date;
import java.util.Calendar;


public class Date_test
{
	
	public static void main(String[] args)
	{
		
		Date today = new Date();

		System.out.println("**** java.util.Date format ****");
		System.out.println(today.toString());
