我正在我的Surface 3上安装JDK，运行64位Windows 10. 正如Core的作者所建议的那样，我在C:\Java\jdk1.8.0_72\上安装了Java，以避免路径名称中的空格。我发誓我已经安装了一个来自这里的这里，而不是JRE。 但是，在设置了环境变量path之后，我打开了命令提示符，输入了javac -version，它告诉我'javac' is not recognized as an internal or external command, operable program or batch file.。所以我检查了C:\Java\jdk1.8.0_72\bin\，没有一个可执行文件名为javac.exe！ 怎么可能呢？我现在该怎么做？   以下是我在dir下运行jdk\bin时的CMD输出 Microsoft Windows [版本 10.0.10240] (c) 2015 Microsoft Corporation.
