NEW QUESTION # 74
Given the fragment:
What is the result?
- A. 0
- B. 1
- C. 2
- D. 3
- E. 4
- F. 5
Answer: A
Explanation:
The two elements 3 and 4 (starting from position with index 2) are copied into position
index 1 and 2 in the same array.
After the arraycopy command the array looks like:
{1, 3, 4, 4, 5};
Then element with index 1 is printed: 3
Then element with index 4 is printed: 5
Note: The System class has an arraycopy method that you can use to efficiently copy data
from one array into another:
public static void arraycopy(Object src, int srcPos,
Object dest, int destPos, int length)
The two Object arguments specify the array to copy from and the array to copy to. The
three int arguments specify the starting position in the source array, the starting position in
the destination array, and the number of array elements to copy.
