This question doesn't appear to have a correct answer:

Given the following declarations:
int a = 5, b = 7, k = 0;
Integer m = null;

and the following statements:
k = new Integer(a) + new Integer(b);  //1
k = new Integer(a) + b; //2
k = a + new Integer(b); //3
m = new Integer(a) + new Integer(b); //4

Executed independent of each other, what will be the value of k (for //1, //2, and //3) and m (for //4) after execution of each of these statements?

The correct answer is:

12
12
12
0

However, this answer isn't one of the choices. The test says that this is the correct answer:

12
12
12
12

But the last one can't be 12, as statement 4 doesn't affect the variable k, and the instructions say that each statement is independent of the others. Therefore, k would still be 0.

The last one is asking you the value of m (not k).
