public class T extends Thread{
	
	public T() {
		this.setName("Thread t");
		this.printName();
	}
	
	@Override
	public void run() {
		this.printName();
		
	};
	
	private void printName() {
		String name = Thread.currentThread().getName();
		System.out.println(name);
	}
	
	public static void main(String[] args) {
		Thread.currentThread().setName("Thread main");
		T t = new T();
		t.start();
	}
}

结果：
Thread main
Thread t
