Hi I have Java class which will read &parse the JSON data from file and insert into DB,they are storing NAME,AGE and PHONE. The program is working fine;But my requirement is ,I have a different JSON data which needs to do same operation,I want to store <strong>AGE</strong>,<strong>ID</strong> and <strong>TYPE</strong>.I have mentioned my JSON data in the last part
I got this code from the <a href="https://javapages4all.wordpress.com/2012/12/10/read-from-json-file-and-persist-into-mysql/" rel="nofollow">https://javapages4all.wordpress.com/2012/12/10/read-from-json-file-and-persist-into-mysql/</a>
test.json:
