Five internal class forms to hide threads in a class

1. Inheriting the thread class with a normal inner class

 Public  class threadtestone {    Private intCountdown =5;PrivateInner Inner;Private  class Inner extends Thread{Inner (String name) {Super(name);        Start (); } Public void Run(){ while(true) {System.out.println ( This);if(--countdown = =0)return;Try{Sleep (Ten); }Catch(Interruptedexception e) {Throw NewRuntimeException (e); }            }        } PublicStringtoString(){return "#"+getname () +":"+countdown; }    } Public Threadtestone(String name) {inner =NewInner (name); }}

2. Construct the thread class with an anonymous inner class, overriding the run () method

 Public classThreadtesttwo {Private intCountdown =5;PrivateThread T; Public Threadtesttwo(String name) {T =NewThread (name) { Public void Run(){ while(true) {System. out. println ( This);if(--countdown = =0)return;Try{Sleep (Ten); }Catch(Interruptedexception e) {Throw NewRuntimeException (e); }                }            } PublicStringtoString(){return "#"+getname () +":"+countdown;        }        };    T.start (); }}

3. Implementing the Runnable class with ordinary inner classes

 Public  class runnabletestone {    Private intCountdown =5;PrivateInner Inner;Private  class Inner implements Runnable{Thread T; Inner (String name) {T =NewThread ( This, name);        T.start (); } Public void Run(){ while(true) {System.out.println ( This);if(--countdown = =0)return;Try{Thread.Sleep (Ten); }Catch(Interruptedexception e) {Throw NewRuntimeException (e); }            }        } PublicStringtoString(){return "#"+thread.currentthread (). GetName () +":"+countdown; }    } Public Runnabletestone(String name) {inner =NewInner (name); }}

4. Construct the thread class using an anonymous inner class, parameter 1 constructs a Runnable object, and Parameter 2 indicates the thread name

 Public classRunnabletesttwo {Private intCountdown =5;PrivateThread T; Public Runnabletesttwo(String name) {T =NewThread (NewRunnable () { Public void Run(){ while(true) {System. out. println ( This);if(--countdown = =0)return;Try{Thread.Sleep (Ten); }Catch(Interruptedexception e) {Throw NewRuntimeException (e); }                }            } PublicStringtoString(){return "#"+thread.currentthread (). GetName () +":"+countdown;        }},name);    T.start (); }}

5. Use local inner classes, that is, construct the thread class inside a method, overriding the run () method

 Public classThreadmethod {Private intCountdown =5;PrivateThread T;PrivateString name; Public Threadmethod(String name) { This. name = name; } Public void Runthread(){if(T = =NULL) {T =NewThread (name) { Public void Run(){ while(true) {System. out. println ( This);if(--countdown = =0)return;Try{Sleep (Ten); }Catch(Interruptedexception e) {Throw NewRuntimeException (e); }                    }                } PublicStringtoString(){return "#"+getname () +":"+countdown;            }            };        T.start (); }    }}
