Description

Guava is the open-sourced version of Google's core Java libraries: the core utilities that Googlers use every day in their code. The Guava utilities have been carefully designed, tested, optimized and used in production at Google. You don't need to write them, test them, or optimize them: you can just use them.

Guava is a productivity multiplier for Java projects across the board: we aim to make working in the Java language more pleasant and more productive. The JDK utilities, e.g. the Collections API, have been widely adopted and have significantly simplified Java code across the board. We hope to continue in that tradition.

We'd also like to mention that:

  • Guava has been battle-tested in production at Google.
  • Guava has staggering numbers of unit tests: as of January 2012, the guava-tests package includes over 110,000 individual test cases. Most of these are automatically generated, not written by hand, but Guava's test coverage is extremely thorough, especially forcom.google.common.collect.
  • Guava is under active development and has a strong, vocal, and involved user base.
  • The best libraries seem obvious in retrospect, but achieving this state is notoriously challenging.

It lets to use some functional idioms in Java. Also it contains some really useful utilities. Highly recommended as an extension to Java standard library.
