Turning an int into a String

[Mike Fourier]

So I've inherited a codebase. And pretty much everywhere that an object returns an int, where a String is desired, I find code like this:

String invoiceId = new Integer(invoice.getInvoiceId()).toString();

Is there some sort of advantage to that code, that I don't understand? I mean: why not just this:

String invoiceId = String.valueOf(invoice.getInvoiceId());

[Paul Clapham]

It's possible that the advantage was simply that the original programmer knew how to write that code but didn't know how to write your suggested replacement.
