Java thread Sleep (), join (), and yield method

An example of the join () method is as follows:

1  Public classthread1{2      Public Static voidMain (string[] args) {3Testthread t=NewTestthread ("T");4 T.start ();5         Try{6T.join ();//similar to calling the run () method.7}Catch(interruptedexception e) {8 9         }Ten          for(inti=0;i<=10; i++ ) { OneSystem.out.println ("I am Main thread!!"); A         } -     } - } the  - classTestthreadextendsthread{ -      PublicTestthread (String s) { -         Super(s); +     } -      Public voidrun () { +          for(inti=0;i<=10;i++) { ASystem.out.println ("I ' M" +getname () + "thread!!"); at             Try{ -Sleep (1000);//sleep () must catch Exception. -}Catch(interruptedexception e) { -                 return; -             } -         } in     } -}

The output is:

1I ' M t thread!!2I ' M t thread!!3I ' M t thread!!4I ' M t thread!!5I ' M t thread!!6I ' M t thread!!7I ' M t thread!!8I ' M t thread!!9I ' M t thread!!TenI ' M t thread!! OneI ' m main thread!! AI ' m main thread!! -I ' m main thread!! -I ' m main thread!! theI ' m main thread!! -I ' m main thread!! -I ' m main thread!! -I ' m main thread!! +I ' m main thread!! -I ' m main thread!!

Yield () Method Example:

1  Public classthread1{2      Public Static voidMain (string[] args) {3Testthread t1=NewTestthread ("T1");4Testthread t2=NewTestthread ("T2");5 T1.start (); T2.start ();6     }7 }8 9 classTestthreadextendsthread{Ten      PublicTestthread (String s) { One         Super(s); A     } -      Public voidrun () { -          for(inti=1;i<=100;i++) { theSystem.out.println (GetName () + ":" +i); -             if(i%10==0){ -Yield ();//when i%10==0, it will yield the CPU. -             }     +         } -     } +}

Output: The current thread T1 (T2) will yield the CPU to T2 (T1) whenever i%10==0 is present.
