平时积累上，要主要把自己解决的难题记录下来，把相关的知识点学透吃透，这样讲出来可能就比较牛逼了，如果实在没有牛逼的亮点。也可以找找你做的项目中别人写的或解决的问题你觉得很牛逼的，把他的源码好好研究几遍，确保学透吃透，就好像是自己做过一遍一样，这样面试时拿出来讲也是很牛逼的，就跟自己做的一样，但是要切记一定要研究明白，否则被问住了就适得其反了。当然最重要的还是自己平时的积累，内功深了自然无招胜有招！

问题1：四种引用类型都是什么？区别是什么？ 2 | #### 参考文章：https://blog.csdn.net/u014532217/article/details/79184412 3 | #### 参考答案： 4 | 强引用-FinalReference~~~强引用是默认引用类型，强引用在程序内存不足（OOM）的时候也不会被回收 5 | 软引用-SoftReference~~~软引用在程序内存不足时，会被回收，内存充足则不回收，用于易造成oom又常用的对象，如图片的bitmap 6 | 弱引用-WeakReference~~~弱引用就是只要JVM垃圾回收器发现了它，就会将之回收，用于易造成oom又不常用或已回收就不需要处理的对象，如handler持有的activity对象 7 | 虚引用-PhantomReference~~~虚引用就是只要JVM垃圾回收器发现了它，就会将之回收，要搭配引用队列使用，回收时会标记引用队列，用于检查对象是否被回收 8 | --------------------------------------------------------------------------------
