 ### Write data with POST and GET methods - PutData.class
+You need to use Handler and post a Runnable. Inside the run method add the code for PutData.
+
+* First we need to create to arrays, one for field name of the parameter and another for the data. Make sure the order is correct.
+```
+String[] param = new String[2];
+param[0] = "param-1";
+param[1] = "param-2";
+String[] data = new String[2];
+data[0] = "data-1";
+data[1] = "data-2";
+```
+* PHP representation, The post array will look like,
+```
+$_POST['param-1'] = "data-1";
+$_POST['param-2'] = "data-2";
+```
+
+* Creating the object for PutData, pass the URL, method, field, data as arguments. The method can be POST and also GET.
+```
+PutData putData = new PutData("https://projects.vishnusivadas.com/AdvancedHttpURLConnection/putDataTest.php", "POST", param, data);
+```
+* Calling startFetch() for starting the process, it returns a boolean value.
+```
+putData.startFetch();
+```
+* To know when the process is completes use onComplete() which returns a boolean value.
+```
+putData.onComplete();
+```
+* If the process is complete, use the getResult() to get the result value.
+```
+putData.getResult();
+```
+* Full implimentation with Handler. You can also add a progress bar at the commended regions.
