I recently read ERP materials. Looking at a lot of RMA, I thought it was RMB. I found the information. In the past, RMA was used to return the goods. Find a detailed one and record it. :RMA (return) Business process RMA has three Processing Methods: repair return repair, replace return, and return. Generally, it is req
The RMA algorithm is divided into three steps:First, the background correction (no energy to write)Second, normalization (no energy to write)Third, calculate the expression valueSuppose there are 5 chips, some of which have 5 probes, and their expression values are as follows:GeneChip4 8 6) 9 73 1 2) 4 5Probe 6 10 7 12 94 5 8) 9 67 11 8) 12 10(1) Get the median of each line:Rdelta4 8 6 9 7 73 1 2 4 5 36 10 7 12 9 94 5 8 9 6 67 11 8 12 10 10(2) Subtrac

Why to use collections and Java Collections Overview Speaker: Wang Shaohua QQ Group No.: 483773664Learning Goals1 Understanding why collections are used2 Mastering the Java Collection frameworkOne, using array defects:
In an electronic pet system, if you want to store multiple pet information, you can use an array. For example, you can define an array of 50 dog
Introduction to common Collections in Java Collections Framework, their features, applicable scenarios, and implementation principles
JDK provides a large number of excellent sets for developers to use. Qualified programmers must be able to select the most appropriate set based on functional scenarios and performance requirements, this requires developers to be familiar with common Java Collection classes.

The difference between Collection and Collections: collections1. java. util. Collection isParent interface of the Collection framework. It provides common interface methods for basic operations on collection objects. The Collection interface has many specific implementations in the Java class library. The Collection interface provides a unified operation mode to maximize various specific sets. CollectionShortlist│ Invalid parameter list│ ├ ArrayList│

Java basic Map interface + Collections tool class, collections tool class
1. In Map, we mainly talk about two interfaces: HashMap and LinkedHashMap.
(1) how to obtain the sorted hashmap
Let's talk about the add, delete, modify, and query functions of Map:
/** Add Map set */Map
The above is the addition, deletion, modification, and query method of Map.
2. Map Traversal

First, ArrayList collection. Add () Adds an object to the element that is actually contained in the Arraylidt. Insert () Inserts an element into the ArrayList at the specified index. can be inserted at any location. Remove () Removes the first occurrence of a specific object from the ArrayList. RemoveAt () Removes the element at the specified index of the ArrayList. Count gets the elements that are actually contained in the ArrayList. Contians () determines whether an element is in ArrayList. In
