Why prefer two's complement over sign-and-magnitude for signed numbers?
...o add them.
Two's complement addition is very simple. You add numbers normally and any carry bit at the end is discarded. So they're added as follows:
0010
+ 1111
=10001
= 0001 (discard the carry)
0001 is 1, which is the expected result of "2+(-1)".
But in your "intuitive" method, adding is m...

What are the big improvements between guava and apache equivalent libraries?
... me attempt to explain why.
Guava is more "modern"
Apache Commons is a really mature library, but it's also almost 10 years old, and targets Java 1.4. Guava was open sourced in 2007, targets Java 5, and thus Guava greatly benefits from the Java 5 features: generics, varargs, enums, and autoboxing....
