Is java suported

[Daniel MD <im-thinking_(_at_)_clix_(_dot_)_pt>]

Hello i'm new to the openBSD, and i would like to know if the freeBSD Java 
port also runs on openBSD, what i really want to know is:

Can i run my Java applications under openBSD ?
Is there any port of a jdk like in freeBSD ?
Will the freeBSD port run under openBSD, since the port system is the 
same(is it the same) ?
Is there any information on Java running under openBSD ?
Is every freeBSD port compatible with openBSD ?

Excuse any mistake, and this lame question, but i could not find any info 
on the openBSD.org site about Java. As i said i'm new in openBSD OS and 
*BSD systems, but i'm familiar to unix (linux).

Thank you all in advanced and have a nice day.
