Question
Select the valid statement to declare and initialize an array.1 point(a) int[] A = {}(b) int[] A = {1,2,3}(c) int[] A = (1,2,3)(d) int[][] A = {1,2,3}
Solution
The valid statement to declare and initialize an array is (b) int[] A = {1,2,3}.
Here's why:
(a) int[] A = {} - This is a valid declaration of an array, but it's not initialized with any values. It's an empty array.
(b) int[] A = {1,2,3} - This is a valid declaration and initialization of an array. The array A is initialized with the values 1, 2, and 3.
(c) int[] A = (1,2,3) - This is not a valid declaration or initialization of an array in Java. In Java, arrays are declared and initialized using curly braces {}, not parentheses ().
(d) int[][] A = {1,2,3} - This is not a valid declaration or initialization of a 2D array in Java. A 2D array would need to be initialized with arrays, not single integer values. For example, int[][] A = {{1,2,3}, {4,5,6}} would be a valid declaration and initialization of a 2D array.
