connecting database and java through jdbc

 Hi

I am new to IntelliJ. I was using the eclipse IDE before. I used the same code from eclipse which was working perfectly fine. but I get a lot of errors in IntelliJ.

I understood how to configure the database seperately from the help pages but I can't connect it through java. Do I have to add some jar file to project like in eclipse? If yes then please let me knoe the full procedure.

Errors:

Exception in thread "main" java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

at JFXDB.JDBC1.main(JDBC1.java:14)

Process finished with exit code 1
