Here is the code, and you can decide which 
(synchronized)StringBuffer or 
faster StringBuilder to use.

Benchmark shows StringBuilder is Faster.

<pre><code>public class Main {
 int times = 777;
 long t;

 {
 StringBuffer sb = new StringBuffer();
 t = System.currentTimeMillis();
 for (int i = times; i --&gt; 0 ;) {
 sb.append("");
 getJSONFromStringBuffer(String stringJSON);
 }
 System.out.println(System.currentTimeMillis() - t);
 }

 {
 StringBuilder sb = new StringBuilder();
 t = System.currentTimeMillis();
 for (int i = times; i --&gt; 0 ;) {
 getJSONFromStringBUilder(String stringJSON);
 sb.append("");
 }
 System.out.println(System.currentTimeMillis() - t);
 }
 private String getJSONFromStringBUilder(String stringJSONArray) throws JSONException {
 return new StringBuffer(
 new JSONArray(stringJSONArray).getJSONObject(0).getString("phonetype"))
 .append(" ")
 .append(
 new JSONArray(employeeID).getJSONObject(0).getString("cat"))
 .toString();
 }
 private String getJSONFromStringBuffer(String stringJSONArray) throws JSONException {

To get a JSONObject or JSONArray from a String I've created this class: 

<pre><code>public static class JSON {

 public Object obj = null;
 public boolean isJsonArray = false;

 JSON(Object obj, boolean isJsonArray){
 this.obj = obj;
 this.isJsonArray = isJsonArray;
 }
}
</code></pre>

Here to get the JSON:

<pre><code>public static JSON fromStringToJSON(String jsonString){

 boolean isJsonArray = false;
 Object obj = null;

 try {
 JSONArray jsonArray = new JSONArray(jsonString);
 Log.d("JSON", jsonArray.toString());
 obj = jsonArray;
 isJsonArray = true;
 }
 catch (Throwable t) {
 Log.e("JSON", "Malformed JSON: \"" + jsonString + "\"");
 }

 if (object == null) {
 try {
 JSONObject jsonObject = new JSONObject(jsonString);
 Log.d("JSON", jsonObject.toString());
 obj = jsonObject;
 isJsonArray = false;
 } catch (Throwable t) {
 Log.e("JSON", "Malformed JSON: \"" + jsonString + "\"");
 }
 }

 return new JSON(obj, isJsonArray);
}
</code></pre>

Example:

<pre><code>JSON json = fromStringToJSON("{\"message\":\"ciao\"}");
if (json.obj != null) {

 // If the String is a JSON array
 if (json.isJsonArray) {
 JSONArray jsonArray = (JSONArray) json.obj;
 }
 // If it's a JSON object
 else {
 JSONObject jsonObject = (JSONObject) json.obj;
 }
}
</code></pre>

I am working on an Android application. In my app I have to convert a string to JSON Object, then parse the values. I checked for a solution in Stackoverflow and found similar issue here <a href="https://stackoverflow.com/questions/5245840/how-to-convert-string-to-jsonobject-in-java">link</a>
The solution is like this
<pre><code> `{&quot;phonetype&quot;:&quot;N95&quot;,&quot;cat&quot;:&quot;WP&quot;}`
 JSONObject jsonObj = new JSONObject(&quot;{\&quot;phonetype\&quot;:\&quot;N95\&quot;,\&quot;cat\&quot;:\&quot;WP\&quot;}&quot;);
</code></pre>
I use the same way in my code . My string is
<pre><code>{&quot;ApiInfo&quot;:{&quot;description&quot;:&quot;userDetails&quot;,&quot;status&quot;:&quot;success&quot;},&quot;userDetails&quot;:{&quot;Name&quot;:&quot;somename&quot;,&quot;userName&quot;:&quot;value&quot;},&quot;pendingPushDetails&quot;:[]}

string mystring= mystring.replace(&quot;\&quot;&quot;, &quot;\\\&quot;&quot;);
</code></pre>
And after replace I got the result as this
<pre><code>{\&quot;ApiInfo\&quot;:{\&quot;description\&quot;:\&quot;userDetails\&quot;,\&quot;status\&quot;:\&quot;success\&quot;},\&quot;userDetails\&quot;:{\&quot;Name\&quot;:\&quot;Sarath Babu\&quot;,\&quot;userName\&quot;:\&quot;sarath.babu.sarath babu\&quot;,\&quot;Token\&quot;:\&quot;ZIhvXsZlKCNL6Xj9OPIOOz3FlGta9g\&quot;,\&quot;userId\&quot;:\&quot;118\&quot;},\&quot;pendingPushDetails\&quot;:[]}
</code></pre>
when I execute <code>JSONObject jsonObj = new JSONObject(mybizData);</code>
I am getting the below JSON exception
<blockquote>
org.json.JSONException: Expected literal value at character 1 of

Please help me to solve my issue.
