Question

We have a configuration where each property maps to two values in the DB,

Ex:

Property Name           Min Value           Max Value

VSMSSUB                   100                500
EEVMSSUB                  100                500

Now, What collection can be used to store the property and there min & max value ? HashMap is not possible since it is one to one.

or

Can I declare like this ?

HashMap

or

Need to use beans ?

Please suggest your recommendations.

Answer 1

You can use a HashMap with the property name as the key and a composite object holding the min and max as value. Example:

public class Value {
   private int minValue;
   private int maxValue;

   public Value(int min, int max) {
      minValue = min;
      maxValue = max;
   }
}

Then create a HashMap as:

HashMap<String, Value> map = new HashMap<String, Value>();

and add key-values:

map.put("VSMSSUB", new Value(100, 500);
map.put("EEVMSSUB", new Value(100, 500);
