Question
Given the following array declarations:String[] aces = new String[] {"black", "gray", "white", "purple"};int acesSize = 4; // the number of elements stored in the aces arrayString[] stripes = new String[] {"blue", "pink", null, "pink", "blue"};String[] flags = new String[] {"yellow", null, "purple", "black"};Which arrays are perfect size?

Solution
In the given question, we are asked to identify which arrays are of perfect size. An array is said to be of perfect size when it doesn't contain any null values and all its allocated memory is being used.
Let's analyze each array:
-
acesarray: It has 4 elements - "black", "gray", "white", "purple". There are no null values and all its allocated memory is being used. So,acesis a perfect size array. -
stripesarray: It has 5 elements - "blue", "pink", null, "pink", "blue". Here, one element is null. So, even though all its allocated memory is being used, it's not considered a perfect size array because it contains a null value. -
flagsarray: It has 4 elements - "yellow", null, "purple", "black". Here, one element is null. So, even though all its allocated memory is being used, it's not considered a perfect size array because it contains a null value.
So, the correct answer is aces array. It's the only perfect size array among the given arrays.
