way to impose constraints on multiple parameters is to check all the parameters that a constraint must hold with multiple setter methods. Once an invalid argument is passed, the constraint fails immediately, rather than waiting for the build method to be called.

You need to chew slowly and have a different experience every time you look.Write a blog here to consolidate.Chapter I.

corresponding domain name queue, send and update the last send time of the changed domain name.2. Unlock the domain to send records.In this way, the non-blocking queue is used for message queue, which improves the concurrency of the system.It seems to solve the problem, but it was blacklisted by some service providers.The system is then analyzed as follows:This is a typical producer-to-consumer issue in which Java client-produced messages are timed t

Leetcode Original question: (That is, to determine whether the binary tree is a two-fork search tree)Given a binary tree, determine if it is a valid binary search tree (BST).Assume a BST is defined as follows: The left subtree of a node contains only nodes with keys less than the node ' s key. The right subtree of a node contains only nodes with keys greater than the node ' s key. Both the left and right subtrees must also be binary search trees The following
