Java Backend Development is a highly in-demand and well-paying job in the tech industry.
If you're looking to become an excellent Java Developer, here's a roadmap that includes various online resources:
1. Core Java
First comes the fundamentals of Java Programming, here you will understand OOP concepts, conditional statements, collection frameworks,and many more.
https://youtube.com/playlist?list=PLd3UqWTnYXOnjGmyjD3zbIkyLXP15-6w0&si=UYvQhVNlZQYCH1Il
2. JDBC
A Java API that allows you to access tabular data, especially data stored in a relational database.
https://youtube.com/playlist?list=PLsyeobzWxl7rU7Jz3zDRpqB-EODzBbHOI&si=Cc45vpeRXGIUKbfn
3. SQL
Get a good understanding of SQL, which is necessary to work with JDBC to write queries.
https://youtu.be/7S_tz1z_5bA
4. JSP + Servlet
Learn JSP and Servlet, which are used for writing web pages for web applications and handling client requests on the server-side.
https://youtube.com/playlist?list=PLE0F6C1917A427E96&si=TQeOIgluG3R29622
