Can I use SparkSQL "java_method" to call my own Java method?

SparkSQL has a way of calling a Java method using the java_method function. The doc has an example like this:

SELECT java_method('java.util.UUID', 'randomUUID');

For my project I'd like to create & call my own Java method - however I don't know whether SparkSQL supports this or not. The doc doesn't mention anything about calling custom Java methods.

So, does anyone know how to accomplish this or has anyone already created & called his/her own Java method with SparkSQL? I'd be really interested to know!

Yes, you can call and pass parameters as well.

You can use the UDF function too using UDF(function name)
