How do we retrieve ec2 client tags

How can I retrieve the tags for ec2 instance using Java aws v2 library. I have been stuck at this for a while. The filter I want to apply is the resource id but its giving me a syntax error

DescribeTagsRequest req = DescribeTagsRequest.builder().filters(new Filter())
