System variables are shared between all the users on the machine. 系统变量在计算机上的所有用户之间共享。 User variables are specific to a single user. 用户变量特定于单个用户。
Ultimately, they will both have the same effect, and the decision should depend on who needs to use Java on the machine. 最终，它们都会产生相同的效果，决定应该取决于谁需要在机器上使用Java。

If you set the path in user variables the path in only visible for the user. 如果在user variables设置路径，则该路径仅对用户可见。 In system variables this path is visible for all users. 在system variables此路径对所有用户都可见。
