Answer

Each element in an array is referred to by their subscript or index. The index of an element refers to the position of an element in the array. In Java, the indices start from 0 and go on till size - 1.

For example,

int arr[] = {3, 6, 8};

In the array arr[], arr[0] = 3, arr[1] = 6 and arr[2] = 8.
