You actually don't need to change that - with the latest version (7 at the moment) you can run code compiled for all older versions, AND for the newest version.
您实际上不需要更改它 - 使用最新版本（目前为 7），您可以运行为所有旧版本和最新版本编译的代码。
What you probably want is to compile your code for use with a older version. See the cross-compilation examplehow to do it with the javaccommand, and this questionfor how to do it in eclipse.
您可能想要的是编译您的代码以用于旧版本。请参阅交叉编译示例如何使用javac命令执行此操作，以及有关如何在 Eclipse 中执行此操作的问题。
