Dear All,

I am facing an issue while iterating Hash Map. Through a query I am fetching list of users and list of emails of those users and i am adding those to a hash map as shown below:

HashMap<ArrayList<String>,ArrayList<String>> valueMap = new HashMap<ArrayList<String>,ArrayList<String>>(); ArrayList<String> userIdList = new ArrayList<String>(); ArrayList<String> emailList = new ArrayList<String>(); valueMap = utilDao.getUserEmailIds(con,details); userIdList = valueMap.get("userList"); //Here it is throwing NullPointer Exception

But the valueMap object contains the required data from the database.
Request to please help me to resolve this issue

Hi Campbell Ritchie/Seetaram,

Please see the below code. Please correct me if im wrong.

for(int newly=0;newly<newList.size();newly++){ for(int old=0;old<oldList.size();old++){ if(newList.indexOf(newly) == oldList.indexOf(old)){ System.out.println("TRUE"); }else{ System.out.println(newList.get(newly)); } } }>

Thanks a lot for your reply. I am trying to fetch the new value from the new list. could you please help me on how to search for the new value in the second list?

Hi all,

I have a scenario, in which, I need to compare with old and new values, which will be 2 different array lists. Also, i need to find the new element or item added in the 2nd array list and print that value. Below is my code snippet.


public class ArrayListTest { public static void main(String[] args) { List<String> oldList = new ArrayList<String>(); oldList.add("Health Care"); oldList.add("Finance"); oldList.add("Production"); List<String> newList = new ArrayList<String>(); newList.add("CME"); newList.add("Finance"); newList.add("CME"); int newListLen = newList.size(); for(int i=0;i<newListLen;i++) { oldList.add(newList.get(i)); } System.out.println(oldList.toString()); int rowslength = oldList.size(); String[] temparray = new String[rowslength]; //To compare the duplicate values whether they occured or not for (int i = 0; i >< rowslength; i++) { boolean flag = false; if (temparray.length!= 0) { for(int temp1 = 0;temp1 < temparray.length;temp1++) { if(temparray[temp1].equals(String.valueOf(i))) flag = true; } } if(flag) continue; for (int j = i + 1; j < rowslength; j++) { if (temparray.length!=0) { for(int temp2 = 0;temp2 < temparray.length;temp2++) { if(temparray[temp2].equals(String.valueOf(j))) continue; } } if ((oldList.get(i)).equals(oldList.get(j))) { temparray[j] = String.valueOf(j); } } } //temparray.sortOn(Array.NUMERIC); //To romove the duplicate elements for(int removeid = 0;removeid<temparray.length;removeid++) { int value = Integer.parseInt(temparray[removeid]); if(value!= 0) { value = value -(rowslength - oldList.size()); oldList.remove(value); } } System.out.println(oldList.toString()); } }

Hi Maneesh,

Thanks a lot for your reply. Say my csv file is having 1000 records. Instead of reading/writing at one shot, I need to read 20 records at one shot, write it to a map and from map write the contents to a new csv file. Im stuck up in the place where i need to check for every 20th record !

Please do the needful.

Hi Campbell,

The code in my previous post will surely throw a compile time exception. I forgot to mention that. But the thing is i need to add those csv contents into map. Then from map i need to write the contents to a new csv file. Could you please help me out in this wit my below code.

Thanks in advance !

Hi Rob,

Thanks a lot for your reply. As per your below reply, I have completed

1) Code to access the file contents
1.a) Code to read the contents line by line
2) Maintain a counter for the number of lines read

Now I need to write the contents that I am reading from csv to a hashmap and then from map to a new csv for every 20 set of records. Please see my code below for your reference.

public class ReadWriteCSV { public static void main(String[] args) { String file = "D:/test.csv"; try{ BufferedReader br = new BufferedReader(new FileReader(file)); Map<Integer,String> values = new HashMap<Integer,String>(); String line = ""; StringTokenizer tokens = null; int lineNo = 0; int tokenNo = 0; //reading the csv file line by line while ((line = br.readLine()) != null) { //increment the lineNo after every line is being read lineNo++; System.out.println("Reading Line No. : "+lineNo); tokens = new StringTokenizer(line, ","); while (tokens.hasMoreTokens()) { //increment the token no! tokenNo++; //Print csv values System.out.print(tokens.nextToken() + " "); //Need to write the values to the hashmap values.put(arg0, arg1); } System.out.println(); //reset token number tokenNo = 0; } } catch(Exception ex){ System.err.println("CSV file not found : " + ex); } } }
