import java.util.Map.Entry;
import java.util.Set;
import java.util.TreeMap;
 
public class Test {
  public static void main(String args[]){
	//Create TreeMap object.
	TreeMap<Integer, String> treeMap = new TreeMap<Integer, String>();
 
	//Add objects to the TreeMap.
	treeMap.put(4, "Roxy");
	treeMap.put(2, "Sunil");
	treeMap.put(5, "Sandy");
	treeMap.put(1, "Munish");
	treeMap.put(3, "Pardeep");
 
	//Print the TreeMap object.
	System.out.println("TreeMap elements:");
	System.out.println(treeMap);
 
	Set<Entry<Integer, String>> entires = treeMap.entrySet();
        for(Entry<Integer,String> entry:entires){
            System.out.println(entry.getKey()+" - "+entry.getValue());
        }
  }
}

Output

TreeMap elements:
TreeMap elements:
