The elements in the two-dimensional array can be a one dimensional array?

You said the "elements" refers to the form, with a subscript or take two subscripts form?
Such as you define an array int [] [] XXX;
XXX [0] is actually an int [] (an int array)
XXX [0] [0] is an int

If you ask is XXX [0] can [0] or an array, then become a three-dimensional array

Is that I met the Object [] [] this two-dimensional arrays, the inside of the element is a multiple one dimensional array, I want to ask, is the only Object array can be in this way, or do any two-dimensional array can put one dimensional array element

is that I've met Object [] [] this two-dimensional arrays, the inside of the element is a multiple one dimensional array, I want to ask, is the only Object array can be in this way, or do any two-dimensional array can put one dimensional array elements when

Because the array itself is also an Object
So the Object can be a one-dimensional array of the elements in an array
Regardless of any other type, even if its internal structure is an array,
Such as an ArrayList, its internal also can be regarded as an array, but still can not send an array directly as the ArrayList [] [] an element

So really only Object [] [] of the elements, can be an array

The Serializable [] [] should also go, array is the default for the Serializable

2 d can be a one-dimensional array of the elements in an array?

Can be any element in the array, even if you are in the 1 d array also can save a 2 d array, think but is a 2 d array is one of the elements,
