Question

Suppose an array-based list uses the following array to store the list items?

int[] array = new int[DEFAULT_CAPACITY];
Then the size of the list is array. length.
a. True
b. False

Answer 1

The statement that an array's length signifies the current size of a list is false; array.length indicates the array's capacity, not the number of elements in the list.

Step-by-step explanation:

The statement "Then the size of the list is array.length" is false. In an array-based list, array.length refers to the capacity of the array, which is the total number of elements the array can hold, not the number of elements currently in the list. The size of the list is typically maintained by a separate variable and indicates the actual number of elements that have been added to the list. It is possible for the size to be less than the capacity if the list is not full, or it could be equal to the capacity if the list is full and no new elements can be added without resizing the array.

The statement is false.The size of the list in this case is not determined by the length of the array, but rather by the number of elements that have been added to the list. The array.length property gives the length of the array, which is the maximum number of elements it can store. To determine the size of the list, you would need to keep track of the number of elements that have been added or removed from the list.For example, if you added 5 elements to the list, the size of the list would be 5, regardless of the length of the array.
