That can be done in a non generic map i suppose(That is not recommended of course). But why would you want to store a integer and String? Or may be you are asking about storing it like Map<Integer,String>?


Cheers!

If you are mimicking a phone book you would want String (=name) as the Key and Integer (=number) as the Value. Only you can't store phone numbers beginning with 0 because they are interpreted as octal.

This can be done in the following manner

import java.util.HashMap;


public class Test2{

public static void main (String args[])
{
HashMap hashMap = new HashMap();
hashMap.put(1, "One");
hashMap.put(2, "Two");
System.out.println(hashMap.get(1));
}

}
