Tree Map with Comparator

#1

can we use tree map with custom comparator of java.util package?

eg:
TreeMap<Integer,Node> hmap=new TreeMap<Node,Integer>(new myComparator());
But this is govong me error

#2

Hy Vidushi , The TreeMap in java uses custom comparator to sort the Map by Key and not Value.
But if you want to sort a map by the value, still we have a solution using LinkedHashMap

#3

You have to update the syntax like this to avoid the error
TreeMap<Node,Integer> hmap=new TreeMap<Node,Integer>(new myComparator());

#4

no no that I have done but it is still giving error

#5 
public class Solution {

	public static void main(String[] args) {
		TreeMap<Node,Integer> hmap=new TreeMap<Node,Integer>(new myComparator());
	}
	

}
class myComparator implements Comparator<Node>{
	 
    @Override
    public int compare(Node e1, Node e2) {
        return e1.value.compareTo(e2.value);
    }
}

class Node{
    
    public String value;
    public int S;
     
}
