Elasticsearch - Point alias from OLD_INDEX to NEW_INDEX

I have an alias which is pointing to my OLD_INDEX. I have a requirement where I am creating a new index and after creation I need to point my alias A to the NEW_INDEX. I need to do this in Java.

I have looked almost everywhere but I cannot find any java implementation for this.

Would really appreciate some help. If possible, it would be great to have a sample code as well.

Thanks.
