what are the jar files are used in a class file.

No jar files are used in a class file.
Where did you see that? Can you post here what you are referring to?

Do u mean the classes from a jar used by the class?

That means

How to know what are the packages are used in a class file.

How to know what are the packages are used in a class file.

Look at the source for the class file
or scan the class file for the classes it references. There are tools to do that.
For example here's the output when I scan a class file using a tool I wrote:

#Searching the classpath for D:\JavaDevelopment\Testing\ForumQuestions3\DemoWin dows
#user.dir is: D:\JavaDevelopment\Testing\ForumQuestions3
#Using classpath: D:\JavaDevelopment\runtime\CheckClassRefs.jar;.
