Java – one of the most popular main-stream programming languages globally – has been in use for almost 20 plus years now. From small mobile applications to large banking applications, all can be developed using Java. It is one of the most portable object-oriented programming languages available. There are other languages too, like C++, D, Scala, Rust, etc. But the complexity of these languages makes them less beginner-friendly.

This is why programmers (both beginners and experienced) worldwide prefer Java over other languages. Why?

Simply because Java has a simple syntax with minimal complexities. No wonder why Java is the tech stack behind numerous applications – advanced games, car navigation systems, medical monitoring devices, parking meters, mobile applications, to name a few.

Learning Java can be an excellent decision if you are a computer science graduate or a programmer keen to improve programming knowledge. There are several resources available both offline and online for learning Java. But the online resources allow you to learn at your own pace and comfort. There are numerous Java courses available online which are up-to-date and comprehensive.

1. Become a Java Programmer

LinkedIn brings you this kit wherein you learn the fundamentals first, find solutions to simple Java programming challenges and then build desktop, mobile and web applications using Java. The kit is divided into nine parts. The first one is about simple Java coding and applications.

The second and third parts are all about building applications and exploring the language. The fourth part deals with the concepts of memory management in Java. In the fifth one, you learn about managing data from relational databases such as Oracle Database, MySQL, and SQL server using Java Database Connectivity( JDBC ) in Java applications.

The sixth and seventh part talks about JPA. JPA ( Java Persistence API ) is the API required to build Java enterprise applications that consist of persistent data. The course covers JPA concepts, including inheritance mapping strategies, the Criteria API, Java Persistence Query Language (JPQL) and a lot more.

Another essential concept of cloud-native Java applications is taught in the eighth part. It deals in building Java applications with the help of Eclipse MicroProfile. And the last one is all about Java interviews and ways to crack them. After finishing the entire kit, you will be ready to enter the industry as a skilled Java developer.
