Java 中一共有 4 种类型的引用 : StrongReference、 SoftReference、 WeakReference 以及 PhantomReference (传说中的幽灵引用 呵呵),
　　这 4 种类型的引用与 GC 有着密切的关系,  让我们逐一来看它们的定义和使用场景 :
1. Strong Reference
　　StrongReference 是 Java 的默认引用实现,  它会尽可能长时间的存活于 JVM 内， 当没有任何]]>https://blog.youkuaiyun.com/cooliceman/article/details/5643051https://blog.youkuaiyun.com/cooliceman/article/details/5643051coolicemanWed, 02 Jun 2010 18:24:00 +0800https://blog.youkuaiyun.com/cooliceman/article/details/5638074https://blog.youkuaiyun.com/cooliceman/article/details/5638074coolicemanMon, 31 May 2010 23:01:00 +0800https://blog.youkuaiyun.com/cooliceman/article/details/5632174https://blog.youkuaiyun.com/cooliceman/article/details/5632174coolicemanSat, 29 May 2010 03:28:00 +0800https://blog.youkuaiyun.com/cooliceman/article/details/5624828https://blog.youkuaiyun.com/cooliceman/article/details/5624828coolicemanWed, 26 May 2010 11:19:00 +0800https://blog.youkuaiyun.com/cooliceman/article/details/3954124https://blog.youkuaiyun.com/cooliceman/article/details/3954124coolicemanTue, 03 Mar 2009 20:30:00 +0800https://blog.youkuaiyun.com/cooliceman/article/details/3096081https://blog.youkuaiyun.com/cooliceman/article/details/3096081coolicemanSat, 18 Oct 2008 15:55:00 +0800
