While one MAY be an alternative for the other, it that they cover the same general functionality, they would still do these same things in slightly/vastly different ways. Also, each one would also do somethings that the other doesn't.

So the decision would probably come down to... Which one covers more of the functionality that you are after in any particular project? It is quite likely that different projects that you are coding will have different requirements and so you would use Google for some projects and Apache for others. We can't really say much more because it is entirely dependant on exactly what you want to achieve.

Also, the last possibilty is that you don't choose between them at all and instead utilise BOTH libraries in the one project, so that some parts of the code can use one and other parts use the other.

In general I think you'll find the Google (Guava) library will be the one to use if you have no strong reason to prefer Apache Commons.

The reason is just that Guava was written more recently - so they had access to everything in Apache Commons and also the Java collection classes when they wrote their libraries.

So usually I think Guava will be the better choice these days, although that's just a rule of thumb.
