Hi

Following is an assignment question in SCJP for java 5 book:


The answer is -434

Can someone explain how ? In what order are the methods called and why?

Start by writing down very carefully what the four methods are, and what their parameters are (ie their signatures)..

Got it sir. Arrays are objects too. hence the -434. Was a tricky one though..

Yes, an array is an object. The Foo[]... versions are equivalent to Foo[][] and you don’t have any arrays of arrays in that code.
