Java getId()方法

getId()方法用于返回线程标识符。线程ID是在创建线程时生成的唯一正数。
线程ID在其生存期内保持不变。当线程终止时,可以重新使用线程的ID。

语法

public long getId()

返回

this method returns the threads ID.

示例

public class GetIdExample extends Thread
{
    public void run()
    {
        System.out.println("running...");
    }
    public static void main(String args[])
    {
        // creating one thread
        GetIdExample t1=new GetIdExample();
        // Returns the identifier of this Thread
        System.out.println("Name of t1: "+t1.getName());
        System.out.println("Id of t1: "+t1.getId());
        // Start the thread
        t1.start();
    }
}
输出:
Name of t1: Thread-0
Id of t1: 21
