public class ThreadTest {
    public static void main(String[] args) throws InterruptedException {
        //1번
        Thread thread1 = new Thread(new Worker("11"));
        Thread thread2 = new Thread(new Worker("22"));        
        
        //2번
        //thread1.setName("A2");
        //thread2.setName("B2");
        
        thread1.start();
        thread2.start();
    }

    private static class Worker implements Runnable {
    	private String name;
    	
    	public Worker(String name) {
    		this.name = name; 	
    	}
    	
        @Override
        public void run() {
