推荐答案

在每次启动时将 SET PATH 命令输入到命令外壳中可能会很快变老.三种选择:

Typing the SET PATH command into the command shell every time you fire it up could get old for you pretty fast. Three alternatives:

1. 从批处理 (.CMD) 文件运行 javac.然后，您可以在 javac 执行之前将 SET PATH 放入该文件中.或者，如果您只需编写 javac.exe
的显式路径，您也可以不用 SET PATH
2. 在系统的环境变量"配置中设置增强的、改进的 PATH.
3. 从长远来看，您会希望使用 Ant 自动进行 Java 编译.但这首先需要对 PATH 进行另一个扩展，这让我们回到 (1) 和 (2).

1. Run javac from a batch (.CMD) file. Then you can just put the SET PATH into that file before your javac execution. Or you could do without the SET PATH if you simply code the explicit path to javac.exe
2. Set your enhanced, improved PATH in the "environment variables" configuration of your system.
3. In the long run you'll want to automate your Java compiling with Ant. But that will require yet another extension to PATH first, which brings us back to (1) and (2).
