Exercise 3.2: printPowersOf2
Write a method called
printPowersOf2 that accepts a maximum number as an argument and prints each power of 2 from 20 (1) up to that maximum power, inclusive. For example, consider the following calls:
These calls should produce the following output:
1 2 4 8 1 2 4 8 16 32 64 128 256 512 1024
You may assume that the value passed to
printPowersOf2 is 0 or greater. (The
Math class may help you with this problem. If you use it, you may need to cast its results from double to int so that you don't see a
.0 after each number in your output. Also, can you write this program without using the
