Update duplicates?

The memory on my laptop hard drive is getting full (too many iPod songs, I guess!) In order to create more space, my computer suggests that I remove some lesser used programs.

Here are my questions: I have Java versions 6, 9, and 10 on my program list. Does version 10 incorporate all the info from 6 and 9? Can I remove versions 6 and 9 without losing valuable Java performance?

Thank you for your help!!
