Java basics-java language overview, java-java Overview I. Two types of computer programming 1. process-oriented model-linear execution is characteristic, and code is considered to act on data. 2. object-oriented model-organizes programs around its data (that is, objects) and the interfaces defined for this data.

Java UDP network programming is implemented mainly through the Datagramsocket and Datagrampacket two classes, the following is an example program,The server listens on UDP 2000 ports and prints the received long type valuesThe client then gets a long value by entering it and sends it to the server Server:/**//* Coding by NYZHL *Import java.net. * ;Import java.io. * ;public class Datagramserver ... {public static void Main (string[] args) ... {Datagram

Pseudo-sharing and cache row filling, from Java 6, Java 7 to Java 8, java There are already a lot of articles about pseudo-sharing. For multi-threaded programming, especially when processing lists and arrays with multiple threads, you should pay attention to the issue of pseudo-sharing. Otherwise, the multi-thread perf
