java - 如何将 arraylist 字符串值加一

Question

有两个 for 循环，我想从内部 for 循环将字符串类型的数组列表值加一。我怎样才能做到这一点？

ArrayList<String> location; //Location and distanceInMiles are ArrayList<String> type and i have store some value into it. 
ArrayList<String> distanceInMiles;
for(String strloc : location){
    for(String strDist : distanceInMiles){
        System.out.println("For Location :" + strloc + "Zip code 30303" + "Distance in Miles:" + strDist);// After print the value i want to increment strDist value by one
        break;
    }
}

    ArrayList<String> location; //Location and distanceInMiles are ArrayList<String> type and i have store some value into it.
    ArrayList<String> distanceInMiles;
    for(String strloc : location){
        ArrayList<String> clone = (ArrayList<String>) distanceInMiles.clone();
        distanceInMiles.clear();
        for(String strDist : clone){
            System.out.println("For Location :" + strloc + "Zip code 30303" + "Distance in Miles:" + strDist);// After print the value i want to increment strDist value by one
            distanceInMiles.add(Integer.parseInt(strDist) + 1 + "");
            break;
        }
    }

希望对你有帮助!
