In K & B SCJP 6, solution I came across a statement "Multidimensional arrays' dimension can be inconsistent". Does it mean that the individual arrays of an array of arrays can have different dimensions? The following is the program:



Does the statement refer to the fact that dd has arrays with 3 and 4 elements?

The solution is 4 (dd[1][2])

That's why a lot of people don't like the term "multidimensional arrays". They are arrays of arrays (of arrays etc).
