Now I am forming the URL in the browser, and execute it via REST api like
localhost:9043/api/json?apiKey=699cccc3dcfb348fd369e083bcd7f2a4&Severity=all
and will get some JSON Object output.
Instead of working on browser, I need to give the URL in the java code itself and to get the json object output also in java code itself. I have searched but not found yet. Need some experts answer for my question.
