Could some one please let me know how to add and read the elements from HashMap?

Thanks

This is simple. HashMap stores key-value pair (both key and value must be an Object).

In order to store a key-value (assume ref is the reference to a HashMap):
ref.put(key, value);

In order to retrieve a value with a key (you can always cast the return value if you know what specified type it is):
Object value = ref.get(key);

I am trying the following sample I am getting error
import java.lang.*;
import java.util.*;
public class Test
{
   public static void main(String[] args)
    {
         HashMap hashmap = new HashMap();
          hashmap.put("type", "INTERACTION_TYPE");
          hashmap.put("code", "PHONE");
          hashmap.put("description", "PHONE");
       
    }
}

Can someone please let me know?

Thanks
