This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I believe that in b 2.3 is truncated to an int value of 2, thus the version of Math.max is the one that takes 2 ints. And in D the -2.8f is widened to a double, thus in this case the version of Math.max is the one that accepts 2 doubles.

Sorry for not including the question. Here it is... Which of the following are valid calls to Math.max? Choose all that apply. A. Math.max(1,4) B. Math.max(2.3, 5) C. Math.max(1,3,5,7) D. Math.max(-1.5, -2.8f) In choice B, I think that the 5 is being implicity converted to a 5.0(double). In choice D, I think that -2.8f is being implicity promoted to a double. Both are invoking the following method signiture, double max(double a, double b). Is this correct? Thanks. Mansi
Correct... The thing to remember here is this order: byte short int long float double So, for example, in option D. we have a float and a double, so we know that float can be implicitly promoted to a double. HTH
