#1 Created at ... [Delete] [Delete and Lock User]

廖老师，说 Collection 是所有集合类的根接口不对吧，Collection 和 Map 是两个不同的继承体系啊

#2 Created at ... [Delete] [Delete and Lock User]

你说得对，Map比较特殊

#3 Created at ... [Delete] [Delete and Lock User]

你再读一遍那句话

#4 Created at ... [Delete] [Delete and Lock User]

原文中说的是Collection是除Map外所有其他集合类的根接口

#5 Created at ... [Delete] [Delete and Lock User]

你说得对! 廖老师说错了！建议直接看源码 java.util.Map 和 java.util.Collection!
