Question 34
Correct Answer: B
The method calls to t.sum(10, 15.25), t.sum(10, 24), and t.sum(10.25, 10.25) invoke the overloaded methods based on parameter types matching the most specific signature. The first call t.sum(10, 15.25) matches the method public void sum(int a, float b), so 'B' is printed. The second call t.sum(10, 24) matches the method public void sum(int a, int b), so 'A' is printed. The third call t.sum(10.25, 10.25) matches the method public void sum(double... a) due to the varargs with doubles, so 'D' is printed. Therefore, the result is 'D A D'.
