Java determine whether the array is empty

One-dimensional array
// one-dimensional array: int [] Array
IF (Array == null || be array.length == 0)
    return to true;

two-dimensional array
// dimensional array: int [] [] Array
IF ((Array == null || be array.length 0 ==) || (. 1 && be array.length == array [0] == 0 .length))
    return to true;

array == null: array is empty
array.length == 0: behavior 0, i.e. {} = Array
be array.length == 1 && Array [0] == 0 .length: 1 acts, as 0, i.e., array = {{}}
