The NIO (New Input/output) class was introduced in JDK1.4, which introduced a channel-based (Chanel)-to-buffers (buf

This article illustrates the merging sort of Java sort algorithm summary. Share to everyone for your reference. The specific analysis is as follows: The merge operation (merge), also called the merge algorithm, refers to the operation of merging two sorted sequences into one sequence. Similar to the quick sort, let's look at merging implementations in

From: http://snowolf.iteye.com/blog/379860 Encryption and decryption were once an important component of my graduation project. After many years of work, it was too simple to recall the encryption and decryption algorithm at that time.To put it bluntly, here we mainly describe some encryption and decryption algorithms implemented by Java, and finally introduce digital certificates.For example, the basic one

pattern string.3. Java implementation of the KMP algorithmThe Java code for the KMP algorithm is given below. The whole algorithm is divided into two parts, one is to solve the next array, and the other is the KMP matching process.public class KMP {/** * Find the next array of a character array * @param t-character ar
