Assume a Java program declares int size = 10; int[] arr = new int[size]; and prints each element in sequence with no separators. Without any assignment to arr, what is printed?

The code will fail to compile 000000000 0000000000 0

Correct Answer:

0000000000

Explanation:

Java initializes arrays of primitive types with default values, and for int that default is 0. Creating an array of length 10 gives you ten elements, all starting as 0. If you print each element in order with no separators, you get ten zeros in a row: 0000000000. The code compiles cleanly because array creation with a size is valid and no assignments change those values before printing. So the observed output is ten zeros concatenated together.
