Thus, it’s preferred to develop applications like software design, gaming technology, and web and mobile applications. Java is an excellent choice for cross-platform applications like web applications, Android apps, cloud applications, machine learning environments, and the Internet of Things. Software development is seldom limited to one language or platform. A Java developer is expected to integrate databases in Java applications. Database connection pool libraries make this interaction a lot faster to process. DBCP enables developers to pool connections rather than creating individual DB connections for every user.
However, be warned of the rabbit holes with various levels of practical value. You really want to learn meaningful skills not just assembling hacks retrieved from google and compiling.
