A Class object used in this fashion is called a type token. public class Context { private final Map<Class<?>, Object> values = new HashMap<>(); public <T> void put( Class<T> key, T value ) { values.put( key, value ); } public <T> T get( Class<T> key ) { return key...

change the signatures of methods, or change inheritance. These restrictions maybe be lifted in future versions. The class file bytes are not checked, verified and installed until after the transformations have been applied, if the resultant bytes are in error this method will throw an exception. ...

我们先看 for 循环遍历处的代码,此处的遍历的内容是 HashMap 是 put 操作节点是为链表时的逻辑:首先这里先判断链表的next节点是否为空,为空则将 put 操作的 key-value 封装为 node 对象,赋值给next节点,然后下一步的判断if (binCount >= TREEIFY_THRESHOLD - 1)是这里的关键,TREEIFY_THRESHOLD 这个是什么呢?
