将JsonNode转换为java数组(Converting JsonNode to java array)

 我正在使用websocket和JsonNode播放frame framewrok 2。 前端通过使用websocket连接到游戏框架后端。 我将javascript数组转换为json节点，并通过使用webscoket连接将其发送到后端。 现在我的问题是我如何将json对象转换为java数组或任何合适的结构，以便我可以操纵数据。 
 
 这是我创建的json对象 
 
var myjeson = {"x":arrayX,"y":arrayY} ;
 
 这是动态填充的数组 
 
 function pixelCount ()
    {  arrayX[counter] = xcoordinate;        
    arrayY[counter] = ycoordinate;
    socket.send(" from array X,Y  "+arrayX[counter]+ " " +arrayY[counter]); 
    ++counter;      
    }
 
 下面的代码发送数据 
 
$('button.send').click(function() {            
sock.send(JSON.stringify(myjeson)); 
 
 在服务器端我有以下代码 
 
 public static WebSocket<JsonNode> givenIn() {
    return new WebSocket<JsonNode>() {
    // called when the websocket is established
    public void onReady(WebSocket.In<JsonNode> in, WebSocket.Out<JsonNode> out) {
    // register a callback for processing instream events             
    in.onMessage(new Callback<JsonNode>() {
    public void invoke(JsonNode event) {                 
    Logger.info(event.toString());
    }
 
 当我检查日志时，消息被传递：下面是日志信息[info]应用程序 - 
 
{"x":
[78.72727298736572,79.72727298736572,82.72727298736572,
7298736572,93.72727298736572,83.72727298736572132.72727298736572],

"y":
[82.6363639831543,82.6363639831543,63.54545593261719,63.54545593261719,64.545455932
61719,65.54545593261719,70.54545593261719,189.5454559326172,188.5454559326172]}
 
 现在我想将这些数据放在一个数组中，以便我可以访问它们。 任何建议都将受到赞赏。另一个建议也欢迎。 

I am working on Play framewrok 2 with websocket and JsonNode . the front end is connected to the play framework backend by use of websocket. I converted a javascript array into a json node and sent it to the backend by the use of the webscoket connection. Now my problem is how do i convert the json object into a a java array or any suitable structure so that i can manipulate the data.
 
this is the json object I created 
 
var myjeson = {"x":arrayX,"y":arrayY} ;
 
this is the array which is populated dynamically 
 
 function pixelCount ()
    {  arrayX[counter] = xcoordinate;        
    arrayY[counter] = ycoordinate;
    socket.send(" from array X,Y  "+arrayX[counter]+ " " +arrayY[counter]); 
    ++counter;      
    }
 
the code below sends the data 
 
$('button.send').click(function() {            
sock.send(JSON.stringify(myjeson)); 
 
on the server side i have the following code 
 
 public static WebSocket<JsonNode> givenIn() {
    return new WebSocket<JsonNode>() {
    // called when the websocket is established
    public void onReady(WebSocket.In<JsonNode> in, WebSocket.Out<JsonNode> out) {
    // register a callback for processing instream events             
    in.onMessage(new Callback<JsonNode>() {
    public void invoke(JsonNode event) {                 
    Logger.info(event.toString());
    }
 
when I check the log the message is delivered : below is the log info [info] application - 
 
{"x":
[78.72727298736572,79.72727298736572,82.72727298736572,
7298736572,93.72727298736572,83.72727298736572132.72727298736572],

"y":
[82.6363639831543,82.6363639831543,63.54545593261719,63.54545593261719,64.545455932
61719,65.54545593261719,70.54545593261719,189.5454559326172,188.5454559326172]}
 
Now I will like to place these data in an array so that I can access them. any suggestion will be appreciated.an alternative suggestion is also welcomed.
