Java ArrayList的ConcurrentModificationException

Java ArrayList的ConcurrentModificationException

如果使用

“ for each”

循环浏览列表，则无法从列表中删除。你可以使用

Iterator

。更换：

for (DrugStrength aDrugStrength : aDrugStrengthList) {    if (!aDrugStrength.isValidDrugDescription()) {        aDrugStrengthList.remove(aDrugStrength);    }}

带有：

for (Iterator<DrugStrength> it = aDrugStrengthList.iterator(); it.hasNext(); ) {    DrugStrength aDrugStrength = it.next();    if (!aDrugStrength.isValidDrugDescription()) {        it.remove();    }}
