Trigger AWS Lambda in Java for the newly uploaded file

I am working on a requirement where I want to trigger the AWS Lambda function written in Java when a file is uploaded on S3 bucket. The condition is that the function should pick-up the latest file in the bucket. Right now, I have the lambda function which picks up the specified file (having already specified file name). But as per the requirement, the file name can be anything(eg. web-log-). Is there any way to do that?

Since with lambda functions, we have access to the event object, can I use it to find out the recently uploaded file?

You could check out the AWS Lambda S3 tutorials, which should show how the uploaded object is passed in as event data. The example code contains a line which should point you in the right direction:

event.Records[0].s3.object.key
