how to retrieve values from map of String and Map

[Anshul Chandra Saxena]

Hi

I have a sample code like this:

  

package com.hsbc.values;

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;
import java.util.Map.Entry;

public class Main {

	public static void main(String[] args) {

		Map valueMap = new HashMap();
		Map mainMap = new HashMap();

		valueMap.put("IBM", "XXXXX");
		valueMap.put("HSBC", "YYY");

		mainMap.put("FIRST", valueMap);
		mainMap.put("SECOND", valueMap);

		
	}
}
 

Can anyone please tell me how to retrieve the values from the valueMap ?As in, for key "FIRST" i want to retrieve the value "XXXXX" .

thanks
Anshul

You'll find the answer int the Collections tutorial!

What strange design. You are adding Maps to Maps. You will have to retrieve a Map, then retrieve a value from it.

There's nothing like easy programming, and that is nothing like easy programming.
