遍历List并删除某个元素

程序中经常会用到遍历list然后删除某一个元素,如果用for循环的话,由于删除元素导致list的长度发生变化,就会导致删除错误或删除失败,这种情况下必须要用到Iterator,具体例子如下:

Iterator<WorkplaceVo> it = workplaceVos.iterator();  
    while (it.hasNext()) {  
        WorkplaceVo workplaceVo = it.next();  
        if (workplaceVo.getId().equals(bespeakVo.getWorkplaceID())) {  
            bespeakVo.setCodeFullPath(workplaceVo.getCodeFullPath());
            it.remove();  
        }  
    }
