You have define the Map to accept String keys and String values, so you can'y put an int as value.

If you are not sure the value type, then Keep it as Object like

HashMap<String, Object> queryValues = new HashMap<String, Object>();

Or, if you know values will be always int only, then define like

HashMap<String, Integer> queryValues = new HashMap<String, Integer>();

Okay, HashMap is expecting two strings. Try doing HashMap<String, Integer> = new HashMap<String, Integer>();

int as generic type? not possible

It would have to be HashMap<String, Integer>.
