JAVA中类型后面跟三个点的使用问题

首先来讲一下java  三个点的知识吧，

可变数组参数。用...的话，传参数时可传可不传，传的话，可以是一个个并列地传，也可以直接是一个数组。
在方法里取时，s是一个数组，如果调用时什么都没有传，那么s的长度就是0。传的时候传了几个，s的长度就是几。
还有，1.5以上才支持这个功能。 
写的例子：

public class ThreePoint {  
    public static void main(String[] args) {  
        printString();  
        System.out.println("==========");  
        printString(new String[] { "我", "和", "你" });  
        System.out.println("==========");  
        printString("我", "和", "你");  
    }  
  
    public static void printString(String... str) {  
        if (str.length == 0) {  
            System.out.println("没有传参数。");  
        }  
        for (int i = 0; i < str.length; i++) {  
            System.out.println(str[i]);  
        }  
        System.out.println("---------------------");  
        for (String s : str) {  
            System.out.println(s);  
        }  
    }  
  
}  

今天，MTBF遇到了一个关于数组越界的问题

这个问题的涉及到java代码如中:

@Override
        protected Void doInBackground(Runnable... params) {
            if (params != null) {
                try {
                    for (int i = 0; i < params.length; i++) {
                        params[i].run();
                    }
                } finally {
                    mHandler.removeCallbacks(mShowProgressDialogRunnable);
                }
            }
            return null;
        }

应该实在异步线程里出现了数组越界的问题：
