Getting element value from jsonpath whose root is an array

Getting element value from jsonpath whose root is an array

hop of those help? You were right to start with the $. However, What you get with your particular JSON is List of HashMap where each JSON Object is represented as a single HashMap. Knowing that you can obtain the list of HashMaps like this:
code :
List<HashMap<String, Object>> jsonObjectsInArray = path.getList("$");
for (HashMap<String, Object> jsonObject : jsonObjectsInArray) {

should help you out It seems that support for returning the length() of an array was only added in version 2.1.0 of the jayway json-path library.
Based on some quick tests, the $.orders.length() expression seems to work with both version 2.1.0 and version 2.2.0, so I think you just need to upgrade your dependency version in order to fix the error you are seeing.
Verify the existence of an array of root nodes with JSONpath

like below fixes the issue The root node operator is $ so you can just read $ into a map and that map will be keyed on your root node names.
For example:
code :
// Approach 1
Map<String, Object> read = JsonPath.read(json, "$");

assertThat(read.size(), is(2));

assertThat(read.keySet(), hasItem("tool"));
assertThat(read.keySet(), hasItem("book"));

// Approach 2: if you want a String[] then ...
String[] rootNodeNames = read.keySet().toArray(new String[read.size()]);
assertThat(rootNodeNames, Matchers.both(arrayWithSize(2)).and(arrayContainingInAnyOrder("book", "tool")));

// Approach 3: if you want to hide it all behind the hasJsonPath() matcher
// note: each of these assertion will cause your JSON string to be parsed 
// so it's more efficient to do that once and assert against the 
// resulting map as I did above
assertThat(json, hasJsonPath("$", Matchers.hasKey("tool")));
assertThat(json, hasJsonPath("$", Matchers.hasKey("book")));

Any of those help As I mentioned in comments JsonPath will read a JSON object and return it like so. It will be like a HashMap with the types being defined by what was parsed. If you, as you mentioned, wants the values as a Json after extracting it you need to convert what was read back to a Json again:
code :
public static void main(String[] args) {
    String response = "{ \"book\": [ " + 
            "      { \"category\": \"\"," + 
            "        \"author\": \"Nigel Rees\"," + 
            "        \"title\": \"Sayings of the Century\"," + 
            "        \"price\": \"\"" + 
            "      }," + 
            "      { \"category\": \"fiction\"," + 
            "        \"author\": \"\"," + 
            "        \"title\": \"Sword of Honour\"," + 
            "        \"price\": \"12.99\"" + 
            "      }," + 
            "      { \"category\": \"fiction\"," + 
            "        \"author\": \"Herman Melville\"," + 
            "        \"title\": \"Moby Dick\"," + 
            "        \"isbn\": \"0-553-21311-3\"," + 
            "        \"price\": \"8.99\"" + 
            "      }," + 
            "      { \"category\": \"fiction\"," + 
            "        \"author\": \"J. R. R. Tolkien\"," + 
            "        \"title\": \"The Lord of the Rings\"," + 
            "        \"isbn\": \"0-395-19395-8\"," + 
            "        \"price\": 22.99" + 
            "      }" + 
            "    ]" + 
    int length = JsonPath.read(response, "$.book.length()");
    Configuration conf = Configuration.defaultConfiguration();

    Object document = Configuration.defaultConfiguration().jsonProvider().parse(response);

    for (int i = 0; i < length; i++) {
        String json = conf.jsonProvider().toJson(JsonPath.read(document, "$.book["+i+"]"));
