I have an HashMap object, which has with key and value pair.
It has 10 keys and values in that object. Now the question
is I want insert new key and value in middle or any where in
that list but not at the end or at the top. Is it possible
or not. If yes how can we achieve this one?

Answer Posted / manoj

package manu;

import java.util.HashMap;



public class Manu_HashMapTest
{
public static void main(String[] args)
{
HashMap<String,Integer> m=new HashMap<String,Integer>();
m.put("a",100);
m.put("b",200);
m.put("c", 300);
m.put("b", 800);//insert a new element....
System.out.println(m);
}
}

o/p->{a=100, c=300, b=800}
so Hash map does not give guarantee in order,so its not
possible to insert element in right position.
