Java Learning (ix): Two ways to implement Java threads

A thread is a single sequential control flow in a program. A relatively independent, scheduled execution unit within a process is the unit of dispatch for the system to dispatch and dispatch CPUs independently of the operating program. Running multiple threads at the same time in a single program accomplishes different tasks, called multithreading.

Process is a computer program on a data set on a running activity, the system is the basic unit of resource allocation and scheduling, is the basis of the operating system structure.

Java threads are created in two ways:

1. Inheriting the thread class

 Public classMyThreadextendsthread{PrivateString name;  PublicMyThread (String name) { This. Name =name; }         Public voidrun () {Try        {             for(inti = 0; I < 5; i++) {Thread.Sleep (100);//increase code Execution timeSystem.out.println ("Thread" + This. Name + ":" +i); }        }        Catch(interruptedexception e) {e.printstacktrace (); }    }         Public Static voidMain (string[] args) {Thread thread1=NewMyThread ("One"); Thread thread2=NewMyThread ("the");        Thread1.start ();    Thread2.start (); }}

Output Result:

Thread one:0threadone: 0thread: 1thread One:1thread one:2thread one: 2Thread One:3threadone: 3thread One:4Thread:4

2. Implement Interface runnable

1  Public classMyThread2ImplementsRunnable2 {3     PrivateString name;4     5      PublicMyThread2 (String name)6     {7          This. Name =name;8     }9     Ten      Public voidRun () One     { A         Try -         { -              for(inti = 0; I < 5; i++) the             { -Thread.Sleep (100);//increase code Execution time -System.out.println ("Thread" + This. Name + ":" +i); -             } +         } -         Catch(interruptedexception e) +         { A e.printstacktrace (); at         } -     } -      -      Public Static voidMain (string[] args) -     { -Thread Thread1 =NewThread (NewMyThread2 ("One")); inThread thread2 =NewThread (NewMyThread2 ("the")); - Thread1.start (); to Thread2.start (); +     } -}

The output is as shown above.
