Pentaho BI suite is completely developed using Java and related open standards. You can not use your existing knowledge in Java to learn BI concepts. What you certainly can is to use you existing knowledge in Java to become a Pentaho BI developer. Being a Java developer is not a requisite, but it might help really a lot for quite a bunch of task,
