Exercise 2
-----------

correct return type  (void)                               [2pts]
correct initialization  for max   (max = arr[0])                [2pts]
correct branch condition for "if" statement (max < arr[i])[2pts]
correct bound check in for loop (i<arr.length)            [2pts]
correct use of avg in println statement  (avg)            [2pts]


Correct program:

	public static void averageAndMax(int[] arr){
		double avg = 0;
		int max = arr[0];
		double sum = 0;
		for (int i=0; i<arr.length; i++){
			sum +=arr[i];
			if (max < arr[i]){
				max = arr[i];
			}
		}
		avg = sum/arr.length;
		println("The average is "+ avg);
		println("The maximum is "+ max);
	}


Exercise 3
----------

Lines that will cause compilation errors: 11 and 12  [2pts]
Reason: you can not assign an object of a superclass to a variable
         of the type of the subclass.  

The following result will be printed to the console:

Hej from class A       [2pts]
Hello from class B     [2pts] 
Hej from class A       [2pts]
Hej from class A       [2pts]
