java如何获取当前线程名称代码实例

通过继承 Thread 类创建一个线程并使用 getName() 方法来获取当前线程名称

package com.gaodaima;

public class ThreadAliveTest extends Thread {
	public void run() {
		for (int i = 0; i < 10; i++) {
			printMsg();
		}
	}

	public void printMsg() {
		Thread t = Thread.currentThread();
		String name = t.getName();
		System.out.println("搞代码运行后的线程名name=" + name);
	}

	public static void main(String[] args) {
		ThreadAliveTest tt = new ThreadAliveTest();
		tt.start();
		for (int i = 0; i < 10; i++) {
			tt.printMsg();
		}
	}
}

package com.gaodaima;

public class ThreadAliveTest extends Thread {

public void run() {

for (int i = 0; i < 10; i++) {

printMsg();

}

public void printMsg() {

Thread t = Thread.currentThread();

String name = t.getName();

System.out.println("搞代码运行后的线程名name=" + name);

}

public static void main(String[] args) {

ThreadAliveTest tt = new ThreadAliveTest();

tt.start();

for (int i = 0; i < 10; i++) {

tt.printMsg();

}

运行结果：
