inquiry how to submit a change

[Vic Wang(BJ-RD)]

Dear,
         It’s my first time to join in this community. I am from ShangHai Zhaoxin Semiconductor Co., Ltd, an X86 CPU product development company.
         Now I want to contribute optimized code to fit our platform, and my target project is jdk8u, should I contribute code to Project jdk10 first?
         In addition, how to submit a change? Should I submit it directly in the mail?

Best Regards!
