We can also put our hands-on small projects and understand how the concepts work concurrently to complete a process.
Know The Emerging Technology Trends
First, you need to understand why Java is so commonly used today by the top developers. Currently, Java code has great performance capabilities as it’s compiled into bytecode and then compiled by the Java compiler.
You should also start learning OOP’s concepts as they are well known in Java. Python bytes objects also have a .hex() method that produces a string that will list the contents as hexadecimal.
- You typically invoke a static type checker as part of the verification step in the build pipeline.
- The work will depend on the level of experience (junior, mid-level, senior).
- In that case, the expression f”The is .” renders the same string for you as the .format() example above.
- Javin paulsaid…Hello John, you can start with the latest 1Z0-819 certification for Java developer and followed by that you can do Spring Professional certification if you like.

However, you need to understand that the topics covered by the book, i.e. concurrency and multithreading, are tricky in themselves. Hence, you will realize later that the strenuous task of going through the book is worth the effort.
Study Guide: How To Prepare For The Backend Skills Assessment
Without having a strong foundation on OOPS, one can’t realize the beauty of an object-oriented programming language like Java. If you don’t have a good idea of what OOPS is, even though you are using the OOP language, you may be still coding in a procedural way. We should know how to apply those principles in designing a solution in an OO way. So, one should have a strong knowledge of object modeling, inheritance, polymorphism, design patterns, etc. Good hold on the OOP and design patterns is essential for writing immaculate Java applications. Head First Design Patterns is one of the leading books to build that particular understanding of the Java programming language. Abstraction in object-oriented programming reduces code complexity by showing only the relevant details of the objects used in the program and enhances code readability.
