Guava is a set of core Java libraries from Google that includes new collection
types (such as multimap and multiset), immutable collections, a graph library,
and utilities for concurrency, I/O, hashing, primitives, strings, and more! It
is widely used on most Java projects within Google, and widely used by many
other companies as well.



Guava comes in two flavors:

import static com.google.common.collect.CollectPreconditions.checkRemove;
import static com.google.common.collect.CompactHashing.UNSET;
import static com.google.common.collect.Hashing.smearedHash;
import static com.google.common.collect.NullnessCasts.uncheckedCastNullableTToT;
import static com.google.common.collect.NullnessCasts.unsafeNull;
import static java.lang.Math.max;
import static java.lang.Math.min;

Wenn Sie nicht wissen, was das ist, werden Sie in den [Sicherheitskapiteln](security/simple-oauth2.md#password-hashing){.internal-link target=_blank} lernen, was ein „Passworthash“ ist.
