1-method A method is a block of code for a series of statements that can alter the state of an object and implement the behavior of a class A method usually can only complete a specific function, which can make the program structure

Policy mode: Behavioral modeThe same behavior, different processing algorithms are encapsulated separately. So they can replace each other.1. Define a super-type interface and behavior method2. Define different implementation classes and implement

Topic:Implement an iterator over a binary search tree (BST). Your iterator is initialized with the root node of a BST.Calling would return the next smallest number in the next() BST.Note: next() hasNext() and should run in average O (1) time and

In Java thread concurrency processing, there is a very big confusion about the use of a keyword volatile, for the use of this keyword, in the multi-threaded concurrent processing can be all right.The Java language is multi-threaded, and in order to
