Java API for completion suggester Index and Mapping commands

Elastic Stack Elasticsearch

Hi,

I am trying to implement completion suggester. I can only see examples using curl commands.
Can somebody please provide Java equivalents of these -

Indexing
curl -X PUT 'localhost:9200/music/song/1?refresh=true' -d '{
"name" : "Nevermind",
"suggest" : {
"input": [ "Nevermind", "Nirvana" ],
"output": "Nirvana - Nevermind",
"payload" : { "artistId" : 2321 },
"weight" : 34
}
}'

Mapping:
curl -X PUT localhost:9200/music/song/_mapping -d '{
"song" : {
"properties" : {
"name" : { "type" : "string" },
"suggest" : { "type" : "completion",
"analyzer" : "simple",
"search_analyzer" : "simple",
"payloads" : true
}
}
}
}'

Thanks
