agile advantages and disadvantages

linked list is better than an array:1. Insert and DELETE operations. Assuming that an element is inserted in the middle of the array, the memory address of all the elements behind the element will be moved backwards. The same is the case with the deletion. Only when the last element of the data is inserted and deleted. It's quicker than that. The list simply needs to change the node information within the node that is necessary to change it. There is no need to change the memory address of the

Functional Organization Advantages:1, strong technical support, easy to exchange, 2, clear career promotion route; 3, straight line communication, simple communication, responsibility and authority is clear; 4. Facilitate repetitive work-oriented process managementThe disadvantages of functional organization:1, the intelligent benefit takes precedence over the project, has the narrow nature, 2, the organiza

store a series of string or integer. So what's the difference in performance between ArrayList and LinkedList?When should I use ArrayList when should I use LinkedList? ArrayList and LinkedList have their own advantages and disadvantages in performance, and each has its own applicable place, which can be described as follows:1. For ArrayList and LinkedList, the overhead of adding an element at the end of th

100000 times, which is 10 times higher than that of MLC flash memory. In addition, in order to ensure the life of MLC, the control chip verifies and the smart wear Balancing Technology algorithm, so that the number of writes to each storage unit can be evenly shared to reach a fault interval of 1 million hours (MTBF ). Internal Structure DRAM-based solid state disks: DRAM is used as the storage medium, and the current application scope is narrow. It imitates the design of traditional hard disk

(); } An object adapter can fit multiple classes with a suitable fit. You only need to pass different matching classes in the adapter construction method. With flexibility. Advantages of class Adapters: 1, because the adapter class is a subclass of the adapter class, it is possible to replace some adapters in the adaptor class to make the adapter more flexible. Disadvantages of class Adapters:

, can be invoked at any time, do not require the developer to do accurate processing, so overuse of session variables will cause code unreadable and difficult to maintain. Although "You can use the session variable directly at any time you want to use it without having to declare it beforehand, this approach is close to the use of variables in VB." After you use it, you do not have to consider releasing it, as it will automatically release. But, "who" thought there? What is the meaning of a var

Recently, several projects have been developed, involving several development modes of android. For the original ecological development, web application development, and hybrid development, I think either of them is the best or the worst. This is based entirely on your own needs, select an appropriate development mode. At the same time, they have their own shortcomings. Based on the actual situation, we should take advantages and avoid

Advantages and disadvantages of sortingClassification: Comprehensive TechnologyReprint program life 23:25:20 I. Bubble Sorting A group of unordered data a [1], a [2],... A [n], which needs to be arranged in ascending order. First, compare the values of a [1] and a [2]. If a [1] is greater than a [2], the values of the two are exchanged. Otherwise, the values remain unchanged. Compare the values of a [2] and
