The compilation error occurred because the print statement is after the 
return statement. The compiler is telling you that it can never be 
executed because the preceding return will have forced an exit from the 
method before the print statement is executed.

The other problem is that, without a print statement in main() you'll 
never know what max3() returned.  Fix those two problems and it will 
work, though calling max3() a few more times (and displaying the result 
each time) with different arguments values with the values in a different 
order will give you more confidence in its correctness.
