    copied!<p>I get the following JSON response from a server...</p> <pre><code>[["1","1"],["2","1"],["3","1"],["4","1"],["5","1"],["6","1"],["7","1"],["8","1"],["9","2"],["10","3"],["11","3"],["12","3"],["13","3"],["14","3"],["15","3"],["16","3"],["17","3"],["18","3"],["19","3"]] </code></pre> <p>It is in JSON format and i get it as a <code>String[]</code>, something like this...</p> <pre><code>String response = Response.getValue(); System.out.println(response) = [["1","1"],["2","1"],["3","1"],["4","1"],["5","1"],["6","1"],["7","1"],["8","1"],["9","2"],["10","3"],["11","3"],["12","3"],["13","3"],["14","3"],["15","3"],["16","3"],["17","3"],["18","3"],["19","3"]] </code></pre> <p>However, the response is a matrix of 2 values <code>[USU_ID, DEPARTMENT]</code> and i need to use it in a <code>String[][]</code>. How can I do this? I tried to use <code>StringTokenizer</code> but it doesn't work very well.</p> <p>This is the code I have written...</p> <pre><code>public static String[][] Json2Matrix(String jsonStringArray) { int i = 0; int j = 0; String[][] mstrJsonString = null; StringTokenizer tokElementos, tokSubelementos, tokTemp; //jsonArray = "[["a","b"],["c","d"],["e","f"]]"; //jsonStringArray = jsonStringArray.replace("\"", ""); //jsonArray = "[[a,b],[c,d],[e,f]]"; jsonStringArray = jsonStringArray.substring(1, jsonStringArray.length() - 2); //jsonArray = "[a,b],[c,d],[e,f]";/ //System.out.println(jsonStringArray); //JSONSerializer.toJSON(jsonStringArray); //System.out.println(jsonArray.toString()); //&lt;editor-fold defaultstate="collapsed" desc="Prueba"&gt; tokElementos = new StringTokenizer(jsonStringArray, "[]"); tokTemp = tokElementos; tokSubelementos = new StringTokenizer(tokTemp.nextToken(), ","); //System.out.println(tokElementos.countTokens()); //System.out.println(tokElementos.nextToken()); //System.out.println(tokSubelementos.countTokens()/2); mstrJsonString = new String[tokElementos.countTokens()][tokSubelementos.countTokens()]; while (tokElementos.hasMoreTokens()) { tokSubelementos = new StringTokenizer(tokElementos.nextToken(), ","); j = 0; while (tokSubelementos.hasMoreTokens()) { mstrJsonString[i][j] = tokSubelementos.nextToken(); System.out.println(i + "," + j + " " + mstrJsonString[i][j]); j++; } i++; } //&lt;/editor-fold&gt; return mstrJsonString; } </code></pre> <p>and i get this as the output...</p> <pre><code>run: 1,0 "2" 1,1 "1" 3,0 "3" 3,1 "1" 5,0 "4" 5,1 "1" 7,0 "5" 7,1 "1" 9,0 "6" 9,1 "1" 11,0 "7" 11,1 "1" 13,0 "8" 13,1 "1" 15,0 "9" 15,1 "2" 17,0 "10" 17,1 "3" 19,0 "11" 19,1 "3" 21,0 "12" 21,1 "3" 23,0 "13" 23,1 "3" 25,0 "14" 25,1 "3" 27,0 "15" 27,1 "3" 29,0 "16" 29,1 "3" 31,0 "17" 31,1 "3" 33,0 "18" 33,1 "3" 35,0 "19" 35,1 "3" </code></pre> <p>It gets the correct values, but the incorrect Indexes. Could someone please help me correct this.</p>
