Consider the following static 2D array declaration int[] list1 = (1,2,3); int[] list2 = {4,5,6); int[] list3 = (7,8,9); int[] matrix (list1,list2, list3); What is shown by the declaration? * It shows a quicker way to declare a 2D static array. A 2D static array is an array of arrays. The initializer list is the best declaration for 2D arrays. The initializer list can only be used with int elements. An incorrect declaration. new should be used for a declaration. Consider the following dynamic 2D array declarations. ArrayList list1= new ArrayList(); list1.add(100); list1.add(200); ArrayList(); list2.add(300); list2.add(400); ArrayList list3 = new ArrayList(); list3.add(500); list3.add(600); ArrayList> matrix = new ArrayList>(); matrix.add(list1); matrix.add(list2); matrix.add(list3); What is shown by the declaration above? * It shows a quicker way to declare a 2D static array A 2D dynamic array is an array of arrays. The initializer list is the best declaration for 2D arrays. The initializer list can only be used with int elements. An incorrect declaration. new should be used for a declaration.
