如何在一個java文件中調用兩個運行方法

Question

下面是代碼，我需要爲2個不同的線程調用2個運行方法，可以這樣做。請幫忙。

public class QuestionList extends ListActivity implements Runnable { 
       //This below thread will call the run method 
     Thread thread = new Thread(QuestionList.this); 
      thread.start(); 

     //can i have one more thread which call run1() method any idea 

} 


public void run() { 


} 

Answer 1

public class QuestionList extends ListActivity { 
        //This below thread will call the run method 
      Thread1 thread1 = new Thread(this); 
      thread1.start(); 

      Thread2 thread2 = new Thread(this); 
      thread2.start(); 


    } 

    class Thread1 implements Runnable 
    { 
     public void run() { 


     } 
    } 

    class Thread2 implements Runnable 
    { 
     public void run() { 


     } 
    }

你不能有兩個過程run()方法，我建議不要使用相同的兩個Thread秒（與if()語句來確定適用的行爲）。

相反，您應該創建兩個不同的類（爲什麼不是內部類）來實現這些不同的行爲。喜歡的東西：

public class QuestionList extends ListActivity { 
    class BehaviourA implements Runnable { 
     public void run() { 
     } 
    } 

    class BehaviourB implements Runnable { 
     public void run() { 
     } 
    } 

    private void somewhereElseInTheCode() { 
     BehaviourA anInstanceOfBehaviourA = new BehaviourA(); 
     Thread threadA = new Thread(anInstanceOfBehaviourA); 
     threadA.start(); 

     BehaviourB anInstanceOfBehaviourB = new BehaviourB(); 
     Thread threadB = new Thread(anInstanceOfBehaviourB); 
     threadB.start(); 
    } 
}  

的好處與內部類是，他們可以訪問的QuestionList的成員，這似乎是你願意做的事情。
