RxJava1 에서 map 반복문

Map<String, String> bodyData = new LinkedHashMap<>();

bodyData.put("key1", "val1");
bodyData.put("key2", "val2");
bodyData.put("key3", "val3");

Observable<Map.Entry<String, String>> entries = Observable.from(bodyData.entrySet());

//사이즈만큼 반복
entries.subscribe( value -> {
   String k = value.getKey();     //키값
   String v = value.getValue();   //밸류
});
