I have a Map which contains +ve and -ve values as key
Map<String,Integer> dr=new TreeMap<String,Integer>();
So i am putting "-1" when putting the negative values. SInce this is a treemap so the values are stored in sorted manner .After i put the values and print the treemap using this function
for (Map.Entry<String, Integer> entry : dr.entrySet()) {
System.out.println(entry.getKey() + ": " + entry.getValue());
}
Output
-1: 4
-2: 3
-3: 5
0: 1
1: 2
2: 5
3: 6
Ideally this should be the output right?
-3: 5
-2: 3
-1: 4
0: 1
1: 2
2: 5
3: 6
How can i acheive this output?
TreeMap sorts using the key. In this case, your key should be Integer, Use Map instead
Map<Integer,Integer> dr=new TreeMap<Integer,Integer>();
and baam , the answer comes. :)
