Using Java in Spark shell

Hello,
A newbie question.
Is it possible to use java code directly in spark shell without using maven to build a jar file?
How can I switch from scala to java in spark shell?
Thanks

I found this:

:javap <path|class>        disassemble a file or class name

But no direct interpretation of Java code.
