Code Simplification, Structure Changes, and Translation Work, Along with a Question

[dukbong]

What's changed?

Description

This PR simplifies the code by using Assert methods and changes the location of the validateParams() process.
By moving this process, validateParams() can perform a null check earlier.

Question

In the JmxCollectImpl code, the getConnectSession() checks whether jmxProtocol.getUrl() != null, which is already validated in validateParams().
This redundancy seems unnecessary, but I'm not entirely sure if I'm missing something, so I left the source code unchanged.
Do you think this extra check is required?

Other Work

This PR also includes translation work, converting text from Chinese to English.

hi this is not redundancy. jmxProtocol.getUrl() is user cutom url, can equlas null.
The validateParams process is to check url whether has sepcial word when it not null.

Thanks for confirming!
I had a feeling there might be something more to it, but I wasn't sure, so I wanted to ask.
