Need to store the result obtained within a while loop for further usage

[Ravi Kiran Va]

Hi ,

Inside a while loop , i am obtaining a result Hashmap as shown

while(--)
{
LinkedHashMap hmFileHeaderIn = (LinkedHashMap)hmFileHeader.get(strFileHeaderIn);
if(hmFileHeaderIn.containsKey(TXN_REC_TYPE))
{
LinkedHashMap hmTxn = (LinkedHashMap) argshmInpFile.get(keyItrHm);
hmTxnForFox = transformatter.formatTransactions(hmTxn, fileId, country, fileSource);
}
}

I am passing this LinkedHashMap "hmTxn" to another Method for some data Formation , by which i obtain a hashmap .

public LinkedHashMap formatTransactions(LinkedHashMap hmTxnSeq,
			String fileId, String country, String fileSource)
			throws Exception 
{
// It returns me an HashMap as shown with somedata put in it .

		return hmTxnForFox;
}

Please let me know how can i store the returned HashMap "hmTxnForFox" so that i can have its values outside the while loop .

If i use list.add(hmTxnForFox) , i am getting only the last value . I want to have all the result outside the while loop

Please help .

Why can't you just create a variable outside the loop?

Thank you very much .

If you put a List outside the while loop you can add hmTxnForFox to it - and then after the while loop is ended you have a List with the found LinkedHashMap.

List<LinkedHashMap> data = new ArrayList<LinkedHashMap>();
while (...) {
   ......
   hmTxnForFox = transformatter.formatTransactions(hmTxn, fileId, country, fileSource);
   data.add(hmTxnForFox);
}
