Updating approved list

Question

Cheers,,,
Please have a look at following:
Approved LIst
1
2
3
4
Waiting List
1-2 > 5-11 //approved as 1 & 2 are in approved list
1-3 > 6 // approved
1-3-2 >7 // approved
1-10-3>8 // NOT approved 10 not present
Updated approved list
1
2
3
4
5
6
7
11 //careful
Any fine way to solve this problem?
This problem might make use of ArrayList, StringTokenizer, Collection
//this code is just to get an idea...
for(int i = 0; i < approvalListno.size(); i++) {
            if((approvalList.get(i)).checkApprovedList(approvedList)) {
                found += i+"-";
            StringTokenizer tok = new StringTokenizer(found,"-");
            while(tok.hasMoreTokens())
                  no = Integer.parseInt(tok.nextToken());
            for(int m = 0; m < approvalList.get(no).getNumWaitingApproval(); m++) {
                 String check = rules.get(no).getApprovedWaiting(m);
                if( !approved.contains(check))
                 approved.add(approvalList.get(no).getWaitingApproval(m).trim());
