I have a small question, given the following snippet:

StringBuilder stringBuild = new StringBuilder(3);  stringBuild.append("hello");  System.out.println(stringBuild+2); // if I omit the (+2) bit hence only stringBUild it works

Does it call automatically toString() on object only in some circumstances? (circumstances: either no operation at all or a previous string contatanation)
