String类型转化成Int类型

Posted 2022-12-06 他叫小黑

String类型通过ASCII规则转化成int类型：String–>byte–>int

ArrayList<Integer> arrayList = new ArrayList<Integer>();
ArrayList vecCmdParam = new ArrayList();

for(int i = 0; i < vecCmdParam.size(); i++)
    Object object = (Object) vecCmdParam.get(i);
    if(object instanceof String)
        byte[] bytes = ((String) object).getBytes();
        for (int j = 0; j < bytes.length; j++)
            arrayList.add((int) bytes[j]);
        
    else if (object instanceof Integer)
        arrayList.add((Integer) object);
