This course is a bit expensive, but you will learn a lot more concepts in-depth, which makes it completely worth your time and money. Kubernetes is a next-level tool and not really needed for all JAva developers, particularly if you are not in DevOps and managing things like scaling and deployment but it’s good to know from a knowledge perspective. If you are creating global applications that show information in many different languages across the world, then you should have a good knowledge of character encodings. You should at least be familiar with essential data structures like an array, linked list, hash table, binary tree, queue, stack, and graph as well problem-solving techniques like dynamic programming. That’s why it’s imperative for Java developers to be familiar with essential Linux concepts and commands related to files, disk space checking, process management, as well as networking commands.

Developed first in 1995 by Sun Microsystems, Java is a concurrent, class-based, and object-oriented programming language based on the syntax of C and C++. 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. Alternatively, software engineers have a broader skillset to work on different programming languages and projects. As Java developers and software developers have similar roles and skills, many professionals transition between the two roles for variety, a new challenge, or to learn new skills.

He worked on projects across numerous industries, from a cloud-based car-dealer-management system for the Volkswagen Group to a CosmosDB explorer at Microsoft. George is also a seasoned interviewer with almost 100 interviews and a strong background in data structures and algorithms. One design goal of Java is portability, which means that programs written for the Java platform must run similarly on any combination of hardware and operating system with adequate run time support. This is achieved by compiling the Java language code to an intermediate representation called Java bytecode, instead of directly to architecture-specific machine code. Java bytecode instructions are analogous to machine code, but they are intended to be executed by a virtual machine written specifically for the host hardware.

Java Developers are responsible for implementing application phases and code in a Java program. They do this by conducting analysis and developing tests of their work.

They work in multi-skilled teams alongside physicists and mathematicians, to determine the best combination of parameter adjustments to meet customer’s goals. Java generics enable programmers to specify, with a single method or class declaration, functionality that can be applied to multiple different data types. Generics also provide compile-time type safety that allows Java programming experts to catch invalid types at compile time.
