The first println statement, System.out.println(array [4][1]);, works fine. It selects the element/array with index 4, {0, 4, 8, 12, 16}, and from this array it selects the element with index 1, 4. Output: 4 The second println statement, System.out.println(array) [1][4]);, fails. It selects the array/element with index 1, {0, 1}, and from this array it try to select the element with index
4. This causes an exception.
Output: 4 Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4
