Answer 1

You define the handler when you deploy the Lambda function. Only the AWS Lambda service needs to know what your custom handler is. So the handler has no relevance in the Java code that is invoking the function. Anything invoking the Lambda function only needs to know the Lambda function name, not the handler name.

In Java you would invoke the Lambda function via the AWSLambdaClient.invoke() method documented here.
