阅读JDK源码的总体规划

阅读目的

1. 从语言设计者的角度重新学习语言
2. 理解常用集合（数据结构）的操作实现细节，记录可能出现的性能瓶颈
3. 学习良好的代码风格

阅读顺序

1. String/StringBuilder/StringBuffer
2. Iterable
3. Comparable
4. AbstractList/AbstractSequentialList/ArrayList/CopyOnWriteArrayList/LinkedList/Stack/Vector
5. AbstractMap/ConcurrentHashMap/ConcurrentSkipListMap/HashMap/Hashtable/LinkedHashMap/Properties/Provider/TreeMap/WeakHashMap
6. AbstractQueue/ArrayBlockingQueue/ArrayDeque/ConcurrentLinkedDeque/ConcurrentLinkedQueue/DelayQueue/LinkedBlockingDeque/LinkedBlockingQueue/LinkedTransferQueue/PriorityBlockingQueue/PriorityQueue/SynchronousQueue
7. AbstractSet/HashSet/LinkedHashSet/TreeSet
8. DataInputStream/FileCacheImageInputStream/FileCacheImageOutputStream/FileImageInputStream/FileImageOutputStream/ImageInputStreamImpl/ImageOutputStreamImpl/MemoryCacheImageInputStream/MemoryCacheImageOutputStream/ObjectInputStream/RandomAccessFile
9. DataOutputStream/FileCacheImageOutputStream/FileImageOutputStream/ImageOutputStreamImpl/MemoryCacheImageOutputStream/ObjectOutputStream/RandomAccessFile

阅读过程

1. 类中提供的常用的API实现
2. 基本上逐行翻译
3. 在类的层次结构设计上有心得可以记录
