DB12c - update java to version 7

Why I used topic like that? I just wanted to post how to update java on Oracle Database 12c from version 6 to version 7. This is simple topic for some people, but it was something new for me today. As we know, Oracle 12c database default java version is 6.
Why do we have to update Java to version 7? Actually, It depends on what application java you write and load into Oracle Database. Unfortunately, it's a bad thing for existing database, you must shutdown database before!!!
