【已解决】Eclipse中用java代码去new Date结果出错：The constructor Date(String) is deprecated

【未解决】Eclipse中调试Java代码期间如何修改值

期间，用代码：

Date newExpiryDate = new Date("Thu Sep 17 14:22:08 CST 2043");

结果出错：

The constructor Date(String) is deprecated

如图：

即：

The constructor Date(String) is deprecated

【解决过程】

1.很明显，Date过期了，不能用了。

所以去找替代者是啥。

2.参考：

去找找关于如何使用Calendar的。

3.找到：

再去试试：

Calendar newExpiryCalendar = new Calendar();

结果又出错：

Cannot instantiate the type Calendar

所以，再参考之前的：

找到：

去改为：

Calendar newExpiryCalendar = new GregorianCalendar();

然后对于上面的时间值：

Thu Sep 17 14:22:08 CST 2043

此处，去改为：

Calendar newExpiryCalendar = new GregorianCalendar(2043, 9, 17);

其中，时分秒就不要了，因为只是为了设置过期时间，所以细节不重要。

3.当然，非要写全，也是可以的：

Calendar newExpiryCalendar = new GregorianCalendar(2043, 9, 17, 14, 22, 8);

【总结】

Java中，不要在用过期的Date，而改用GregorianCalendar，对应的用法：

Constructor Summary
`GregorianCalendar()` Constructs a default GregorianCalendar using the current time in the default time zone with the default locale.
`GregorianCalendar(int year, int month, int date)` Constructs a GregorianCalendar with the given date set in the default time zone with the default locale.
`GregorianCalendar(int year, int month, int date, int hour, int minute)` Constructs a GregorianCalendar with the given date and time set for the default time zone with the default locale.
`GregorianCalendar(int year, int month, int date, int hour, int minute, int second)` Constructs a GregorianCalendar with the given date and time set for the default time zone with the default locale.
`GregorianCalendar(Locale aLocale)` Constructs a GregorianCalendar based on the current time in the default time zone with the given locale.
`GregorianCalendar(TimeZone zone)` Constructs a GregorianCalendar based on the current time in the given time zone with the default locale.
`GregorianCalendar(TimeZone zone, Locale aLocale)` Constructs a GregorianCalendar based on the current time in the given time zone with the given locale.

比如：

import java.util.GregorianCalendar;
Calendar newExpiryCalendar = new GregorianCalendar(2043, 9, 17, 14, 22, 8);

即可。
