Need help with java map and javabean
- by techoverflow
Hi folks,
I have a nested map:
Map<Integer, Map<Integer, Double>> areaPrices = new HashMap<Integer, Map<Integer, Double>>();
and this map is populated using the code:
while(oResult.next())
{
Integer areaCode = new Integer(oResult.getString("AREA_CODE"));
Map<Integer, Double> zonePrices = areaPrices.get(areaCode);
if(zonePrices==null)
{
zonePrices = new HashMap<Integer, Double>();
areaPrices.put(areaCode, zonePrices);
}
Integer zoneCode = new Integer(oResult.getString("ZONE_CODE"));
Double value = new Double(oResult.getString("ZONE_VALUE"));
zonePrices.put(zoneCode, value);
myBean.setZoneValues(areaPrices);
}
I want to use the value of this Map in another method of the same class. For that I have a bean.
How do I populate it on the bean, so that I can get the ZONE_VALUE in this other method
In my bean I added one new field as:
private Map<Integer, Map<Integer, Double>> zoneValues;
with getter and setter as:
public Map<Integer, Map<Integer, Double>> getZoneValues() {
return zoneValues;
}
public void setZoneValues(Map<Integer, Map<Integer, Double>> areaPrices) {
this.zoneValues = areaPrices;
}
What I am looking for to do in the other method is something like this:
Double value = myBean.get(areaCode).get(zoneCode);
How do I make it happen :(
