Anything that is not a primitive is already an Object. Therefore, Map<String,Integer> is a Map<? extends String,? extends Object>, and you can use it in the putAll method:

// Map<String,Integer> integerMap
// Map<String,String> stringMap
Map<String,Object> objectMap = new HashMap<String,Object>();
objectMap.putAll(integerMap);
objectMap.putAll(stringMap);

Also, most Map implementation classes have a constructor that takes a Map<? extends K,? extends V> so it's even shorter for only one map:

Map<String,Object> objectMap = new HashMap<String,Object>(integerMap);
