Reference的另一个子类——软引用——可满足一个不同却相关的目的。
Softly reachable: an object that is not strongly reachable and can be accessed through a soft reference.
软可及对象(softlyreachable)：不是强可及对象，并且能够通过软引用访问的对象。

Soft Reference . When an object holds only soft references, GC collects it only if there is not enough memory.
软引用 。当一个对象只具有软引用时，垃圾回收器只在内存不足的时候才回收它。

The key to whether a soft reference can be used is whether an application can recover from the loss of the data being cached.
是否可使用软引用的关键在于，应用程序是否可从大量缓存的数据恢复。
Weak and soft references both extend the abstract reference class (as do phantom references, which will be discussed in a future article).
弱引用和软引用都扩展了抽象的reference类(虚引用(phantomreferences)也一样，这将在以后的文章中介绍)。
CachingChecksum used a soft reference to cache a single object and let the JVM handle the details of when to evict the object from the cache.
CachingChecksum使用一个软引用来缓存单个对象，并让JVM处理从缓存中取走对象时的细节。
Just as with weak references, a soft reference can be created with an associated reference queue, and the reference is enqueued when it is cleared by the garbage collector.
正如弱引用一样，软引用也可创建为具有一个相关的引用队列，引用在被垃圾收集器清除时进入队列。
Reference queues are not as useful with soft references as with weak references, but they could be used to raise a management alert that the application is starting to run low on memory.
引用队列对于软引用来说，没有对弱引用那么有用，但是它们可以用于发出管理警报，说明应用程序开始缺少内存。
The idea of a SoftReference is that you hold a reference to an object with the guarantee that all of your soft references will be cleared before the JVM reports an out-of-memory condition.
SoftReference的原理是：在保持对对象的引用时保证在JVM报告内存不足情况之前将清除所有的软引用。
If a finalizer (final queue) is associated with a soft or weak reference, then only after the soft or weak reference is removed is the finalizer removed on the next GC pass that is run.
如果一个finalizer (final查询)与一个soft或weak引用相关，那么只有当这个soft或weak引用删除后，这个finalizer才会在所运行的下一个GCpass上被删除。
