推荐答案

Hello Dejanx，

Hello Dejanx,

1。确保添加了"％JAVA_HOME％\ bin;"到你的PATH环境变量。

2."java -version"但不是"java-version"。命令"java"之间有一个空格。和参数"-version"。

1. Make sure you have added "%JAVA_HOME%\bin;" to your PATH environment variables.
2. "java -version" but not "java-version". There is a space between command "java" and parameter "-version".

祝你好运，

Best regards,
