Importing class libraries
One thing that's not super human-readable about our program is the long paths to functions such as pow() and println(). Is there a way we could shorten them? There certainly is. If the makers of Java had wanted to, they could have allowed us to call this function by simply typing Math.pow() in all instances. This unfortunately would have some unintended side effects. For example, if there were two libraries linked up to Java and they both declared a Math.pow() function, Java would not know which one to use. Hence, by default, we're expected to link to libraries directly and explicitly.
So, if we'd like to just be able to type out something like Math.pow(), we can import a library into the local space that we're working ...
