[Map<Integer,ArrayList<String>>]question
I am building a map with the key as an integer and a list of string as the
value ; basically this is the stripped code :
import java.util.Map;
import java.util.HashMap;
import java.util.TreeMap;
import java.util.ArrayList;
public class map {
public static void main(String args[]) {
ArrayList<String>clonableDataList=new ArrayList<String>();
Map<Integer,ArrayList<String>>clonableDataMap= new
HashMap<Integer,ArrayList<String>>();
for (int i=0;i<3;i++) {
clonableDataList.removeAll(clonableDataList);
clonableDataList.add(Integer.toString(i));
clonableDataList.add(Integer.toString(i+1));
clonableDataMap.put(i,clonableDataList);
System.out.println("key="+Integer.toString(i)+"list="+clonableDataList+"**");
}
for (Map.Entry <Integer,ArrayList<String>>
entry :clonableDataMap.entrySet()) {
ArrayList<String>aa=new ArrayList<String>(entry.getValue());
System.out.println("key="+Integer.toString(entry.getKey())+"list="+entry.getValue()+"**");
}
}
}
when I run the code I get this :
key=0list=[0, 1]**
key=1list=[1, 2]**
key=2list=[2, 3]**
[2, 3]
key=2list=[2, 3]**
[2, 3]
key=1list=[2, 3]**
[2, 3]
key=0list=[2, 3]**
so apparently I get all the time the same list "2, 3" for all the the
different keys when printing my map ; what is wrong ?
Thanks.
