从集合中删除时如何避免ConcurrentModificationException

Question

我正在迭代它时，我的数组列表的删除命令出现问题。如何解决ConcurrentModificationException？

protected void deleteModeOfPayment(List<List<String>> AllModeOfPayment) {
    int ctr=0;
    List<String> thePayments =new ArrayList<String>();
    Iterator<List<String>> ia=allModeOfPayment.iterator();
    while(ia.hasNext()){
        thePayments=ia.next();
        String refOne= thePayments.get(1).toString().trim();
        if(refOne.equals(referenceIdentity)){
            log.d("ALVIN","ITEM TO BE DELETE FOUND");
            allModeOfPayment.remove(ctr);
        }
        else{
            ctr++;
            log.d("ALVIN","ITEM TO BE DELETE NOT FOUND");}
        }
    }
}

使用迭代器删除元素 -

ia.remove();
