Calling wslite RESTClient from java?

[lowrider59]

Can I get some help here?

I have some groovy-classes, I'm trying to rewrite to Java.

The groovy-code uses wslite for REST-calls, and follows this pattern:

JsonBuilder request = createRequest();
Map<String, Object> params = createParams();
RESTClient client = new RESTClient(endpoint);
Response response = client.put(params) ( it -> { text(request); });

How do I rewrite the final line with the Closure part?

What is the Java equivalent?
