I think you're looking for:

if(someCondition) builder.id("1ac");

The id method is written so that you pass it the value you want to set and then it returns this so you can chain calls together to set different values with a single statement.

I think you're looking for something more like this:

String idNew;    

public Builder id( String val )     
{             
  idNew = val;
  return idNew;     
} 

if(blah blah)
{
  id("1ac");
}

Or, of course, what the guy above me said. Either or.

You are returning a String when the method is meant to return a Builder.
