有沒有辦法改變啓動的Thread的名字？

Question

有沒有辦法改變開始的Thread或Thread.setName(String name)的名稱只能在線程初始化塊中使用？

Answer 1

您可以在您的代碼的任何部分仍然有引用原始線程，並且只要SecurityManager允許它。

Answer 2

該函數被稱爲setName（String name）;

Thread t = new Thread(...); 
t.start(); 
t.setName("..."); 

Answer 3

線程名稱可以使用Thread.currentThread().setName

public class NamedThreadExample implements Runnable { 

    public static final String THREAD_NAME_GOES_HERE = "Original Name"; 
    public static final String NEW_THREAD_NAME_GOES_HERE = "New Name"; 

    public void run() { 
    System.out.println("I am a Thread and my name is " 
         + Thread.currentThread().getName()); 

    Thread.currentThread().setName(NEW_THREAD_NAME_GOES_HERE); 

    System.out.println("I am a Thread and my name is " 
         + Thread.currentThread().getName()); 
    } 

    public static void main(String args[]) { 
    (new Thread(new NamedThreadExample(), THREAD_NAME_GOES_HERE)).start(); 
    } 
} 

事實產生輸出後也實例化Thread對象時設置

I am a Thread and my name is Original Name 
I am a Thread and my name is New Name
