How to save data in another table in android?

Hi! In Parse.com it was so:

ParseObject post = new ParseObject("Chat");
post.put("Message", message);
post.saveInBackground();

If i try to save data like this:

Backendless.Persistence.save( contact, new AsyncCallback<Contact>() {
 public void handleResponse( Contact response )
 {
 // new Contact instance has been saved
 }
 
 public void handleFault( BackendlessFault fault )
 {
 // an error has occurred, the error code can be retrieved with fault.getCode()
 }
 });

then data will be saved in Contact table. How I can change a destination table?
