Test: Arrays - Grade 11 MCQ

Array contains elements only of the same type.

Note that int arr[]; is declaration whereas int arr[] = new int[3]; is to instantiate an array.

Array indexing starts from 0.

ArrayIndexOutOfBoundsException is a run-time exception and the compilation is error-free.

Arrays store elements of the same data type and present in continuous memory locations.

Since there are 15 int elements and each int is of 4bytes, we get 15*4 = 60bytes.

Elements in an array are accessed randomly. In Linked lists, elements are accessed sequentially.

This is the syntax to initialize an array in C.

The syntax to declare multidimensional array in java is either int[][] arr; or int arr[][];

Trying to access an element beyond the limits of an array gives ArrayIndexOutOfBoundsException.
