You could use the Apache HTTP Client library to perform RESTful (JSON requests/posts).

Here is a tutorial how to do a post/get to an Alfresco like server: RESTful Java client

Replace the example url's with the Alfresco urls defined in the Workflow REST API. Furthermore before you do all this, you need to authenticate to Alfresco.

1. Use the same HTTP Client example to get the ticket with url http://localhost:8080/alfresco/service/api/login?u=admin&pw=admin
2. You will get a response like: <ticket>TICKET_887add1e01b5c4c0cd58ac11c768f8e54c1eabf4</ticket>
3. Save the ticket value of the element in a Java variable
4. Use the ticket with one of the workflow REST API services e.g. http://localhost:8080/alfresco/service/api/workflow-definitions so present the Ticket like following: http://localhost:8080/alfresco/service/api/workflow-definitions?alf_ticket=TICKET_887add1e01b5c4c0cd58ac11c768f8e54c1eabf4
5. Do whatever you'd like with the result :)
