推荐答案

Java的一个卖点是一次编写，随处运行（几乎）。

One of Java's selling points is that is is "Write Once, Run Anywhere" (pretty much).

编译的字节码由Java虚拟机（JVM）执行。 JVM特定于其运行的平台，但任何具有JVM的平台都可以执行相同的字节码。代码不必重新编译。

The compiled bytecode is executed by the Java Virtual Machine (JVM). The JVM is specific to the platform that it runs on but the same bytecode can be executed by any platform that has a JVM. The code does not have to be recompiled.

Swing是Java的跨平台GUI工具包。您可以对其进行配置，使其具有在不同平台上看起来相同的GUI（它们在任何平台上看起来都不是原生的），或者您可以告诉它使用最适合它的平台的外观正在执行。因此，如果您在Windows上运行它将看起来像一个Windows应用程序，如果您在OS X上运行它将看起来像一个原生的Mac应用程序。

Swing is Java's cross-platform GUI toolkit. You can configure it so that it has a GUI that looks the same across different platforms (it won't look native on any of them), or you can tell it to use the most appropriate look-and-feel for the platform that it is executing on. So if you run on Windows it will look like a Windows app, if you run on OS X it will look like a native Mac app.
