第59行的注释 " * 在转变成树之前,还会有一次判断,只有键值对数量大于 64 才会发生转换。" HashMap中写的是对的,ConcurrentHashMap中的 MIN_TREEIFY_CAPACITY转换的时候也是用的tab.length比较的 所以不应该是键值对 而是table的长度为64
414 行3.3“如果链的长度大于TREEIFY_THRESHOLD这个临界值”改为:“如果链的长度大于等于TREEIFY_THRESHOLD这个临界值”
if (binCount >= TREEIFY_THRESHOLD - 1) // -1 for 1st treeifyBin(tab, hash); break;
