Question

I have two values in my hashmap… How can i access those values without using for loops..

This is my hashmap code:

HashMap<Integer, Integer> obMap = new HashMap<Integer, Integer>();
obMap.put(new Integer(1),PartnerID);
obMap.put(new Integer(2),numwidgets);
return obMap;

I am returning values to java script method…how to read values in JSP if i get in obMap.

Answer 1

HashMap<Integer, Integer> obMap = new HashMap<Integer, Integer>();
obMap.put(1,PartnerID);
obMap.put(2,numwidgets);
System.out.println(obMap.get(1));
System.out.println(obMap.get(2));

Note you don’t need new Integer(1). It’s autoboxing.
