即使在编写这个类的同时也许正在编写一个特定的应用程序，该类一样可以在组织的任何项目中使用。
Although this class was written perhaps while a specific application was written, the class can be used by any project in the organization.
在这个例子中所使用的约定是，使用一个和合成要素名称一致的类图表，并且在包含该合成要素的包中，显示它的外部视图。
The convention used in this example is to use a class diagram with a name that is the same as the component, and, in the package containing the component, to show its external view.
修改的类装入器使用看上去几乎与普通类文件完全一样的模板文件，不同的是这个模板文件在常量池中有一些“洞”，在装入时为每个实例化类填充这些“洞”。
A modified class loader USES template files that look almost exactly like ordinary class files except for "holes" in the constant pool that are filled in at load time for each instantiation class.
因为您需要在其他包内使用来自这个包的两个类，您将需要导出其在清单中的包。

Scientists next plan to upgrade HARPS hardware and software and use the instrument to conduct a more refined search of nearby sunlike stars for rocky Earthlike planets that could support life.
注意，这个相同的类，只要更改包名和类名，就可以在您的每个GAE项目中使用。
Note that this same class, with changes for package name and class name, can be used in each of your GAE projects.
当你有足够多的功能需要归并到一个类里，并且这个类在仅会被外层类所使用时，一个嵌套类就非常有用。
A nested class make sense when you have enough related functionality to lump together in a class, but the functionality is only ever going to be used by its "outer" class.
在这个工程中有一些数据包装类和从属类用来在真实情景中演示典型的类路径问题(尽管在这个工程中使用它们是多余的)。
There are some data wrapper classes and dependent classes in this project to demonstrate typical classpath issues in a real scenario (although their use is superfluous in this project).
为了使用这个处理程序，您需要确保WASv5WSAExtensions. jar在Web服务客户端应用程序的类路径中。
To use the handler, you need to ensure that WASv5WSAExtensions.jar is on the classpath of the Web services client application.
例如，Invoice类会有grandtotal属性，这个属性由其实例在计算时使用，但它不保存到数据库中。
For example, an Invoice class may have a grandTotal attribute that is used by its instances for calculation purposes, but that is not saved to the database.
在这个例子中，还可以使用适当的数据库名，在称为dbName 的派生业务对象类中声明私有String属性。
In this example, a private String attribute can also be declared in derived business object classes, called dbName, with the name of the appropriate database.
而且，因为两个映射的类(Building和Land)是从estate中继承而来，所以我们可以在HQL查询中使用这个抽象超类，如清单14所示。
And, since our two mapped classes (Building and Land) inherit from Estate, we can use this abstract superclass in our HQL queries, as shown in Listing 14.
您可以使用HTML元素来在另一个web页面中显示web页面，我们正好利用这一优势来创建一个新extbrowserwindow类，该类可以在Ext . Window中显示这个web页面。
You can use the HTML element to display web pages inside another web page, so we'll take advantage of that to create a new ExtBrowserWindow class that will display this web page inside an Ext.Window.
在我使用alpha版时，我还不得不直接使用会员类手工为这个表单编写代码。
Since I'm using the alpha bits, though, I'll have to code this particular form by hand using the Membership class directly.
当我使用Groovy插件的时候，我必须能够在包中声明我的领域类，然而JetBrains插件不能处理这个问题。
When it comes down to it I must be able to declare my domain classes in packages and the JetBrains plugin can't handle that.
在使用某个类名时，Ruby会检查是否已经从类路径中加载了相同名称的类，如果是，则会在第二次操作时重新打开这个类。
When you use a class name, Ruby checks to see if it has already loaded a class from the classpath by that same name and, if it has, the second occurrence reopens the class.
包含一个用类写入响应的输出流。请遵守HTTP协议在适当的时候使用这个流。
