There are innumerable algorithms that you must learn to start with the development job role. Integrated Development Environments (IDEs) are software applications that provide a comprehensive set of tools for developers to write, edit, debug, test, and deploy code more efficiently. The IDEs for Java typically refer to a space where developers can write and edit Java code, fix errors by debugger, and directly compile and run Java applications from within the IDE, by testing of code. SQL is a classic and probably the most valuable skill for any software developer.

Architectural Patterns
Mockito is a mocking framework that’s particularly useful for creating mock objects in unit tests. It lets you create dummy objects called mocks to simulate behaviour and interactions. If your code interacts with a database, you can use Mockito to “pretend” you’re accessing a database without actually doing so.
Since the modern application has a lot more data, many of them are switching to NoSQL for faster retrieval and increased scalability, and that Java Programmer with NoSQL skill is in demand. Since Java applications have heavily relied on the library, including JDK, a mocking framework like Mockito is always needed to write a test that can run in isolation. The basic principles of service-oriented architecture are independent of vendors, products, and technologies. It sounds very similar to microservice, where also the application is divided into multiple services, but the key difference is size, microservice, as the name suggests, is much smaller in size and scope. The latest version of Java EE is Java EE 8, and if you want to learn Java EE, this list of the best Java EE Courses from Udemy, Pluralsight, and LinkedIn Learning is the best to start with.

- For designing Java applications, understanding object-oriented programming concepts is very important.
- With its versatility, reliability, and security, Java is used in various industries and applications, from web and mobile app development to enterprise applications and embedded systems.
- Java is a powerful programming language that has existed for over two decades and is still going strong.
- Most of the applications you will write like Web applications or Mobile apps will also not be standalone but client-server kind of application where the request will go through the network to a server.

- Arrays and collections are two important concepts in Java programming.
The most common skill I’ve seen in successful developers is having the ability to quickly write code, run, analyze, debug, recode, and restart on problems. The faster a developer can get through that loop (like the Orient-Observe-Decide-Act loop in combat), the more information she develops and better decisions get made. This process is good during initial development, but becomes even more valuable in late-stage development of complex systems and deployed applications. Other developers often get stuck analyzing the problem, attempting to work out the logic tree in their head, or have trouble reproducing the condition and give up. I think Git and GitHub should be the most essential tools that all Java programmers learn and master.
