I used okhttp library to call API Calls on a website of mine based on WordPress. In that call, I forgot to close connection in the end and called various endpoints on the loop. Next morning I saw that the CPU and RAM usage was still high even after 6 hours of performing calls, which led me to infer that the possibility is that I forgot to close the connections and when I checked I saw I forgot to call response.body().close()
Now here is am thinking, doesn't the server close the connection automatically and release resources after a certain time if I don't close connection manually?
I am facing a dilemma here. Earlier I used to use Core Java Library HttpUrlConnection to get JSON data over the web and use to parse it with GSON. Earlier these days my university teacher told me to use Retrofit library instead. Thinking of it a better and optimized way to code, I started working with it.
I loved its simplicity and rich feature but here I am struggling a lot due to of Callback anonymous inner class. Due to of it I am unable to pass the objects to other methods of mail application files, which I used to handle easily when I worked with HttpUrlConnection. Now here is my question, am I going any wrong, or is it really not a wise decision to use Retrofit with my java applications and I should stick to HttpUrlConnection.
Please let me know!
I am pasting a code below just to explain my point here:

I am wondering what are the applications of java EE. I know we can make a website with help of servlets and JSP but that can be accomplished with PHP as well, then what is the benefit of coding a website in java when it can be done in a much simpler way in PHP. Also thinking as a client, one would ask the programmer to code in PHP than java as JAVA web hosting are way too expensive than simple shared hosting plans on which PHP website can run. Then what is the real benefit of JAVA?
I have started learning java EE a few days ago and I am wondering if I had made a correct decision. Please let me know what are the benefits of a website/web-app over other languages maybe PHP or .net. Also I there any other purpose of java other than the website building. Are there any popular applications which are built solely on java?
I am very confused if I has chosen the right path. Thanks in advance.
