How to create S3 bucket in AWS lambda function using Java

Question

I am trying to create a S3 bucket and upload some data into S3 buckets. But I have few questions about AWS Lambda service.

1. How to create, delete, upload s3 bucket using AWS Lambda function (Java)?
2. I am using React native as a front-end so I have to call a lambda API call to create the s3 bucket or doing something in the backend. And my question is, can I use different languages in both sides? (ie React is my front end and Java is my backend).
