007--多线程

第一个小例子

public class TestRunable {

    
    public static void main(String[] args) throws InterruptedException {
        TestRunable aRunable = new TestRunable();
        aRunable.testOne();
        aRunable.testTwo();
        aRunable.testThree();
        
    }
    
    private void testOne() throws InterruptedException {
        ExecutorService cachedThreadPool = Executors.newCachedThreadPool();  
        for (int i = 0; i < 10; i++) {  
            final int index = i;  
            Thread.sleep(index * 1000);  
            cachedThreadPool.execute(new Runnable() {  
            @Override  
            public void run() {  
                System.out.println(index);  
            }  
            });  
        }
    }
    private void testTwo() {
        System.out.println("222222222222222");
    }
    private void testThree() {
        System.out.println("333333333333333");
    }
}
