Can you possibly clarify this purpose a little more? The boundaries for these are easily looked up.

Purpose: To learn the boundaries of int and long (accuracy), to become more familiar with the java libraries.

In addition the Java 1.4 link is a bit dated, correct? You are taken to a 'End of Life' page.

Thank you,

Hi Jeremy,

Indeed, they are easy to look up - so that part of the assignment is quickly accomplished.

And what you might do when you need something beyond that boundary.

I'm curious to know what the Instructor did in the 35 lines of code. My solution was 13 lines. And, I never did figure out what I was suppose to find the API (whatever version). What am I missinig?

For one thing, the cattle drive specifies java 1.4. the printf method you use is not available until 1.5.

second, your code does not conform the Style guide.

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
