disassemble object in array

I have a search method in the database that brings me the following result:
As you see that inside the Object [4] comes another array containing People, Pessoas, and PessoasEnderecos and more objects that have relantionship with Pessoas.
I would like it to return only this way and not inside another array as it is happening now, it should look like this:
elementData=Object[10](id=144)
[0]=Pessoas(id=166)
[1]=PessoasEnderecos(id=167)
...
i have this method:
#RequestMapping(method = RequestMethod.GET, value = "/pessoas")
public ResponseEntity<Collection<Pessoas>> buscarPessoas(HttpServletRequest request) throws Exception {
String idEntidadeCrypt = request.getHeader("DataBase");
Long idEntidade = Long.parseLong(Crypto.decode(idEntidadeCrypt));
Collection<Pessoas> pessoasBuscados = pessoasService.buscarFiltro(idEntidade);
return new ResponseEntity<>(pessoasBuscados, HttpStatus.OK);
}
and :
#Repository
public interface PessoasRepository extends JpaRepository<Pessoas, Integer> {
#Query( value="select pes, pEnd, pFis, pJur "
+ "from "
+ "Pessoas pes, "
+ "PessoasEnderecos pEnd,"
+ "PessoasFisicas pFis,"
+ "PessoasJuridicas pJur"
+ " where "
+ "pes.entidade.idEntidade = pEnd.entidade.idEntidade "
+ "and pes.idPessoa = pEnd.pessoa.idPessoa "
+ "and pes.entidade.idEntidade = pFis.entidade.idEntidade "
+ "and pes.idPessoa = pFis.pessoa.idPessoa "
+ "and pes.entidade.idEntidade = pJur.entidade.idEntidade "
+ "and pes.idPessoa = pJur.pessoa.idPessoa "
+ "and pes.entidade.idEntidade = :parametroId " )
public Collection<Pessoas> encontrar(#Param("parametroId") Long usuarioEntidade);
how can i solve that ?

ArrayList<> does not work with magic, it has an actual implementation. elementData is the array where it stores its elements. As you can see (that is a link in the previous sentence), it is a private member of the class, so you do not interact with it, but you see it in a debugger because it exists.
If you want to return an array instead of a List, you can always use toArray() which all Lists implement.

Elements of a split string array can't be used as function inputs?

Here is my code:
// This is the bug - this works.
String[] lst = {"desk", "pencil"};
String lst0 = lst[0];
System.out.println("path: " + lst[0]);
System.out.println("result: " + root.getDirectory(lst0).getFileName());
// This is the bug - this doesn't work.
String[] ef = "desk/pencil".split("/");
String ef1 = ef[0];
System.out.println("path: " + ef1);
System.out.println("result (without getFileName): " + root.getDirectory(ef1));
But in the second case, the function isn't called properly, as ef[0] seems considered differently from lst[0] by the compiler despite both being strings. I assume this is becaue lst is a array that resulted from list splitting. Is there any way to fix/work around this?

JAVA - is it possible to filter the sub elements of JSON Object that is large & recursive ??

I want some help to find a quick solution for my problem. Given a json object that is large with a recursive model. I want to list the JSON sub elements & its immediate parent Object( only the sub object which satisfies the given key value condition).
Ex :
{
Object : {
id : "0001",
parent:"A",
child: {
id:"0001A",
Country:"US",
parent:"B",
child:{
id:"0001AA",
Country:"UK",
parent:"C",
child:{
id:"0000AAA",
Country:"US",
parent:"D",
child:{
.........
}
}
}
}
}
}
I want to list the id's of the subObject whose country is 'US' and it's parent id..
is there available any readymade plugins to handle these kind of scenarios in JAVA , without using object mappers/custom class objects..
Ps provide any possible idea ..

Yes, it is possible write code using the Jackson Tree Model API which would traverse a JSON tree and select the nodes that satisfy criteria. Here is an example:
public class JacksonTree2 {
public static final String JSON = "{\"Ex\" : {\"Object\" : {\n" +
" \"id\" : \"0001\",\n" +
" \"parent\":\"A\",\n" +
" \"child\": {\n" +
" \"id\":\"0001A\",\n" +
" \"Country\":\"US\",\n" +
" \"parent\":\"B\",\n" +
" \"child\":{\n" +
" \"id\":\"0001AA\",\n" +
" \"Country\":\"UK\",\n" +
" \"parent\":\"C\",\n" +
" \"child\":{\n" +
" \"id\":\"0000AAA\",\n" +
" \"Country\":\"US\",\n" +
" \"parent\":\"D\",\n" +
" \"child\":{\n" +
" \n" +
" }\n" +
" }\n" +
" }\n" +
"\t}\n" +
"}}}";
public static void main(String[] args) throws IOException {
ObjectMapper mapper = new ObjectMapper();
JsonNode root = mapper.readTree(JSON);
for (JsonNode node : root.findParents("Country")) {
if ("UK".equals(node.get("Country").asText())) {
System.out.println(node.get("id"));
break;
}
}
}
}
Output:
"0001AA"

iterate over a set and create a string containing HTML

I have the following code that is used in the Image gallery generating program Jalbum to generate all keywords used for the images in the gallery.
Set allKeywords = new HashSet();
for (AlbumObject ao : currentObjects) {
XmpManager mgr = ao.getXmpManager();
if (mgr != null) {
allKeywords.addAll(mgr.getKeywordSet());
}
}
//get the Iterator
Iterator itr = allKeywords.iterator();
while(itr.hasNext())
out.println(itr.next());
My question is when out.print:
out.println(itr.next());
how can I add html to each individual keyword? I basically want to outprint:
keyword
I am a newbie in this realm so please be gentle!

out.println("" + itr.next() + "");
If you want to call iterator.next() two times
out.println("<a href=\"#\" class=\"label list2\""
+ " data-filter=\"" + "." + itr.next() + "\">"
+ (itr.hasNext() ? itr.next() : "") + "</a>");
For your requirement I hope mgr.getKeywordSet() returns string
String str = itr.next();
System.out.println("<a href=\"#\" class=\"label list2\""
+ " data-filter=\"" + "." + str + "\">" + str + "</a>");

Adding the results to an arraylist

I am facing some difficulties while assigning the values in an array list. My code is :
while (answer.hasMore()) {
SearchResult rslt = (SearchResult)answer.next();
Attributes attrs = rslt.getAttributes();
System.out.println();
if (attrs.get("department") != null && attrs.get("telephonenumber") != null) {
System.out.println(attrs.get("department") + " " + attrs.get("name") + " " +
attrs.get("Description") + " " + attrs.get("mail") + " " +
attrs.get("telephonenumber")+
attrs.get("samaccountname") + attrs.get("samaccountname") );
}
I want to assign the values of attrs.get("department") + attrs.get("description")+ attrs.get("name")+attrs.get("mail") each one to an array list.
I tried to define at the beginning:
String[] name = new String[100];
and in the while loop i tried to read the name attribute, I tried to do:
name = attrs.get("name");
But it did not work. Can anyone help.

In Java, an array and an ArrayList are quite different.
String[] name_array = new String[100];
creates a fixed-length array of Strings, but
ArrayList name_list = new ArrayList();
creates a variable-length ArrayList of objects (it will grow as you add more objects).
To add an object to an ArrayList, you can use its add() method.
name_list.add("Hello");
However, with an array you need to set the object at a specific index, e.g:
name_array[23] = "Hello";
You need to read a basic tutorial on the Java language and standard library.

You cannot directly assign strings to a array made of string "references". You need to index it first. But it would be much better to actually use a list (and maybe convert it to an array later). Check out List and ArrayList in the Java documentation.
As an example:
Attributes attrs = new Attributes();
List<String> attribValues = new ArrayList<String>();
System.out.println();
if (attrs.get("department") != null
&& attrs.get("telephonenumber") != null) {
System.out
.println(attrs.get("department") + " " + attrs.get("name")
+ " " + attrs.get("Description") + " "
+ attrs.get("mail") + " "
+ attrs.get("telephonenumber")
+ attrs.get("samaccountname")
+ attrs.get("samaccountname"));
attribValues.add(attrs.get("department"));
attribValues.add(attrs.get("telephonenumber"));
}
final String[] attribArray = attribValues.toArray(new String[attribValues.size()]);

First of all define your name as String not as an array of String like this:
String name;
And then read name as:
name = attrs.getString("name");
Now coming back to your issue of populating List, I am sure you will get ready-made answers here but I suggest you to do some reading on how to create and populate a List in Java.
