Java

Get Stock Orders

We will first import the "java.io", "java.util", "java.net" and "org.json" packages.

Next, we create a public class "GetStockOrders".

Inside the public class, we will create a public static void, and declare all the input and output variables.

Then we create a try clause, and create the header object.

Then, we will connect to the API serviceName, build the request parameters, send the request, and get the response object.

Then we will parse the Content, ServiceResponse, and ServiceRespHeader, and store the "GlobalErrorID", "ErrorText" and "ErrorDetails" in "globalErrorID", "errorText" and "errorDetails" respectively.

If the globalErrorID is '010041', it means that the OTP provided has expired. We will then display the errorText and errorDetails as well as a message 'OTP has expired, new OTP will be sent'.

If it is not '010000', we will display the ErrorText and the ErrorDetails.

Else, it means that there is no error, and we will use the "instanceof" operator to check whether the "stockorders" object is an JSONArray or JSONObject, and display the results accordingly.
