yeah I think it is an errata... Typical cut-paste problem... I'm moving this to Mock Exam Errata
I met the same question in John Hunt Mock exam. Could anyone explain to me why --------------------------- Boolean flag = true; // 3 --------------------------- is not acceptable? Thanks a lot!

because: Boolean flag = true tries to assign the boolean literal true to a reference variable of type Boolean (which is a class)... boolean flag = true and Boolean flag = new Boolean("true") Boolean flag = new Boolean(true) are valid statements.
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
