Learning Essentials

1. Relationship of processes and threads

2. Multithreaded program run mode

3. Methods for defining threads

Multi-Threading vs. Multi-process

Multi-process: Multiple programs can run concurrently in the operating system

Multithreading: There are multiple sequential streams in a program that execute simultaneously

Methods for creating threads

Method 1: Define a thread class that inherits the class thread and overrides the method run (), which is called the thread body

Because Java only supports single inheritance, classes with this method can no longer inherit from other classes

Class Firstthread extends thread{//firstthread inherit threadpublic void Run () {//Replication Run method for (int i = 0; i<100; i++) {Syste M.out.println ("Firstthread--->" + i);}}}

Interface test{public static void Main (String args[]) {//Generate thread class object Firstthread ft = new Firstthread ();//Start thread ft.start ();// The thread state for (int i = 0; i<100; i++) {System.out.println ("Main--->" + i);}}}
