since you are on windows, java doesn't work like that. there is a java.exe in some windows directory (%windir% system32 for you)
因为你在 windows 上，java 不能那样工作。在某些 Windows 目录中有一个 java.exe（%windir% system32 给你）
This java.exe actually looks in the registry HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment
这个 java.exe 实际上在注册表中查找 HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment
PATH won't help ya! Since I tend to get lazy I delete the JRE and create a junctionto the JDK instead.
PATH 帮不了你！因为我比较懒惰，所以我删除了 JRE 并junction为 JDK创建了一个。

make sure that your JRE/bin directory is not included in your path. the first instance of java.exe found while searching your path will be the one that is executed. if you've added your JDK to the path after the JRE then the JRE will always be picked.
确保您的 JRE/bin 目录不包含在您的路径中。搜索路径时找到的第一个 java.exe 实例将是执行的那个。如果您已将 JDK 添加到 JRE 之后的路径中，则将始终选择 JRE。
you can also explicitly specify the full path to java.exe when invoking java. this will ensure that you always know what java jre/jdk you are invoking.
您还可以在调用 java 时显式指定 java.exe 的完整路径。这将确保您始终知道您正在调用什么 java jre/jdk。

If you have a 64bit operating system, it will try to use the 64bit jre that is preinstalled on windows 7. You can try using add/remove programs to remove the 64bit jre. I've had this problem several times and I've always fixed it by removing the 64bit jre.
如果您使用的是 64 位操作系统，它会尝试使用 Windows 7 上预装的 64 位 jre。您可以尝试使用添加/删除程序来删除 64 位 jre。我已经多次遇到这个问题，我总是通过删除 64 位 jre 来解决它。
