What is the result of compiling and running the following code?

public class Test{
        public static void main(String[] args){
                int[] a = new int[0];
                System.out.print(a.length);
        }
}

In Java arrays are

A. objects

B. object references

C. primitive data type

D. None of the above

Which one of the following is a valid statement?

What is the result of compiling and running the following code?

public class Test{
        public static void main(String[] args){
                int[] a = new int[0];
                System.out.print(a.length);
        }
}

A. 0

B. Compilation error, arrays cannot be initialized to zero size.

C. Compilation error, it is a.length() not a.length

D. None of the above

What will be the output?

public class Test{
        public static void main(String[] args){
                int[] x = new int[3];
                System.out.println("x[0] is " + x[0]);
        }
}

A. The program has a compile error because the size of the array wasn't specified when declaring the array.

B. The program has a runtime error because the array elements are not initialized.

C. The program runs fine and displays x[0] is 0.

D. The program has a runtime error because the array element x[0] is not defined.
