Answer 1

If your Objects are containing of Strings only, then you can do it like this:

Map map = new HashMap(); //Object is containing String
Map newMap =new HashMap();
for (Map.Entry entry : map.entrySet()) {
       if(entry.getValue() instanceof String){
            newMap.put(entry.getKey(), (String) entry.getValue());
          }
 }

If every Objects are not String then you can replace (String) entry.getValue() into entry.getValue().toString().
