for   (int   i   =   0;   i   <   l.size();   i++)   {
    String[]   str   =   (String[])l.get(i);       //这是100行

------解决方案--------------------
你的list里至少有一个不是String[]类型
------解决方案--------------------
java.lang.ClassCastException；类型不匹配

String[] str = (String[])l.get(i); //这是100行
强制转换出了错
------解决方案--------------------
java.lang.ClassCastException类转型异常
你先把list中每个对象输出来看看啊
System.out.println(l.get(i));
应该有不是String型的
------解决方案--------------------
