I think you have put command like java -VERSION. This is in capital letters
You need to put all command in lowercase letters
我想你已经把命令像java -VERSION. 这是大写字母你需要把所有命令都用小写字母
javac -version
java -version
All characters must be in lowercase letter
所有字符必须是小写字母

--versionis a valid option from JDK 9 and it is not a valid option until JDK 8 hence you get the below:
--version是 JDK 9 中的有效选项，它在 JDK 8 之前不是有效选项，因此您会得到以下信息：
Unrecognized option: --version
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
You can try installing JDK 9 or any version later and check for java --versionit will work.
您可以尝试安装 JDK 9 或以后的任何版本并检查java --version它是否有效。
Alternately, from the installed JDK 9 or later versions you can see from java -helpthe below two options will be available:
或者，从已安装的 JDK 9 或更高版本中，您可以看到java -help以下两个选项可用：
-version print product version to the error stream and exit
--version print product version to the output stream and exit
where as in JDK 8 you will only have below when you execute java -help
与在 JDK 8 中一样，当您执行时，您将只有以下内容 java -help
-version print product version and exit
I hope it answers your question.
我希望它能回答你的问题。
