It also defines relationships between data values so that the values can be easily manipulated. Data Structures and AlgorithmsĪ data structure is an assembly of data values that are organized, managed, and stored in a particular format. Since Java is an Object-Oriented Programming language (OOP), you need to know about polymorphism, inheritance, abstraction, encapsulation, and other OOP concepts. Java can be your first programming language to learn, but you should first be familiar with the following computer science concepts: OOP Concepts To learn Java, you must have a little idea about computer science. If you learn Java, it also becomes easier for you to learn any other OOP based programming language in less time. Most of the Android phones have their operating system written in Java, which is about 88% of the total global smartphone market. By learning Java, you get to code in Core Java and move in the direction of becoming a JavaScript expert, a web application developer using J2EE and related web technologies, principal architect, designer, and so on. San Francisco and Arlington pay the highest salaries to their Java developers with about $97000 per year on an average.īecause of its many advantages and unique features, Java was still the most preferred language even after its first release 25 years ago. Many websites and web applications continue to be built on the Java platform, thus keeping the demand for Java developers and designers always on the higher side.Īs per PayScale, a developer's average salary range is $47,169 to $106,610 per year. It is also the right choice for data science and machine learning, of course, after Python and R. Java has a lot of security features and cross-platform capabilities. Since Java is object-oriented, the code is split into independent modules, making the code reusable and free from bugs. Java is platform-independent at the source-code and binary levels, which means the code you compile once can be used anywhere. You can perform any task in Java as there are rich libraries and plugins. Learning Java has a lot of advantages when compared to other languages. Why Should You Learn Java?īefore you know how to learn Java, you should be convinced about why you should learn it! Also, most graduates learn about C/C++ as part of their curriculum, so learning Java becomes easy and this blog post wil give you a detailed guidelines about how to learn java programming. The product is free, and open-source adds to its popularity. It is compatible and versatile and used for mobile, desktop, and web applications, games, web servers, application servers, database connection, client-side validations, and many more. Java is used in almost all domains like retail, finance, healthcare, logistics, etc. Java is a robust, statically typed, safe, class-based programming language that has been ruling the web for some time. Java is among the top programming languages of 2023. Sometimes it feels like a sales pitch.ĭisclosure: I received a copy of this book from the publisher in exchange for writing this review on behalf of CodeRanch.Ramya Shankar | 21 Mar, 2023 How To Learn Java (Step by Step Guide) Sometimes this is helpful – the preview/setup videos are free. He also plugs the companion Udemy course a lot. But I would definitely recommend it for someone who wants to start coding and get the lay of the land. So I wouldn't recommend this book for someone who wants to become a professional programmer. For example, the book used close at the end of a try rather than in a try with resources (or even finally.) That might have been because the syntax was so basic. It covers how to run the examples with Java 8 and 9. The book starts with easy programming concepts and advances to more complex ones as it goes through the chapters. He even covers how to produce a runnable jar. He covers jshell for quick learning which is good early on. The author explains some concepts like user experience as he goes. There's also a lot of emphasis on user interfaces for both Java and Android. Both with programs like MadLibs and by experiment with making changes to the code. I think the target audience of the book is either older students or adults who don't have a coding background. While “Learn Java the Easy Way” is certainly readable by middle schoolers. I had read “Teach your Kids to Code” by the same author and expected “Learn Java the Easy Way” to be similar.
