Different ways to get HashMap elements

package myutil;

import java.util.*;
public class HashMapEx1  { 
    

       public static void main(String... args) {
            HashMap map=new HashMap();
            map.put("orange",new Integer(1000));
            map.put("apple",new Integer(2000));
            map.put("banana",new Integer(3000));
            map.put("grapes",new Integer(4000));
            System.out.println("The Map "+map);
            System.out.println(map.put(("orange"),new Integer(1001)));
            System.out.println("map "+map);
            //using key set
            Set s=map.keySet();
            System.out.println("The Key Set"+s);
            // using values
            Collection values=map.values();
            System.out.println("The Values Are "+values);
            // entry set
            Set s1=map.entrySet();
            System.out.println("The Entry Set"+s1);
            //iterator
            Iterator it=s1.iterator();
            while(it.hasNext())
            {
                Map.Entry m1=(Map.Entry)it.next();
                System.out.println(m1.getKey()+"........"+m1.getValue());
                if(m1.getKey().equals("apple")){
                    m1.setValue(new Integer(6000));
                System.out.println(m1.getValue());
                }
            }
                
    }
}

output:
The Map {orange=1000, grapes=4000, apple=2000, banana=3000}
1000
map {orange=1001, grapes=4000, apple=2000, banana=3000}
The Key Set[orange, grapes, apple, banana]
The Values Are [1001, 4000, 2000, 3000]
The Entry Set[orange=1001, grapes=4000, apple=2000, banana=3000]
orange........1001
grapes........4000
apple........2000
6000
banana........3000
