Re-learning Java Basics (iv): Creating and executing threads

1. Inherit thread

　　

 Public class extends thread{    publicvoid  run () {        System.out.println () {Thread.CurrentThread (). GetName ());    }          Public Static void Main (string[] args) {        new  testthread ();        T.start ();    }}

2. Implement Runnable

 Public class Implements runnable{    @Override    publicvoid  run () {        System.out.println ( Thread.CurrentThread (). GetName ());            }      Public Static void Main (string[] args) {        new Thread (new  testrunnable ());        T.start ();    }}

3. Thread pool

 Public classTestthreadpool { Public StaticExecutorservice Singlepool =Executors.newsinglethreadexecutor (); Private StaticExecutorservice Fixedpool = Executors.newfixedthreadpool (2); Private StaticExecutorservice Cachedpool =Executors.newcachedthreadpool (); Private StaticThreadpoolexecutor TPE =NewThreadpoolexecutor (5, ten, Timeunit.seconds,NewLinkedblockingqueue<runnable> (),NewDefaultthreadfactory (),NewThreadpoolexecutor.abortpolicy ()); Private Static classDefaultthreadfactoryImplementsthreadfactory{@Override Publicthread Newthread (Runnable r) {thread T=NewThread (R); returnT; }    }         Public Static voidMain (string[] args) {Singlepool.execute (Newtestthreadp ()); Fixedpool.execute (Newtestthreadp ()); Cachedpool.execute (Newtestthreadp ()); Tpe.execute (Newtestthreadp ()); }        }classTestthreadpImplementsrunnable{@Override Public voidrun () {System.out.println (Thread.CurrentThread (). GetName ()); }    }
