What is output with the statement System.out.println(x+y); if x and y are int values where x=10 and y=5?
a) 15
b) 105
c) 10 5
d) x+y
e) An error since neither x nor y is a String
Answer: a. Explanation: Java first computes x+y and then casts it as a String to be output. x + y = 10 + 5 = 15, so the statement outputs 15.
