Java is inspired by C and C++ and uses an object-oriented programming model, which means that concepts or things are represented as "objects" that have data fields and methods. One of the biggest advantages of Java is that it runs on a Java Virtual Machine (JVM), meaning that you can execute Java code on any platform that has a JVM, without re-compilation. This is different from C and C++, which require re-compilation for every hardware platform you execute the code on. Java has many other advantages, including automatic memory management. This eliminates hard-to-understand pointers used in languages like C, which can help Java developers write better code in a shorter period of time.What does it mean that Java is an object-oriented programming language?Java is an object-oriented programming (OOP) language, which means concepts or things are represented as "objects" that have data fields and methods. In object-oriented programming, models called "objects" represent either a programming entity or an abstract concept. These objects are created and assembled independently of one another but can work with each other in logical ways. Objects are manifestations of classes and can inherit code allowing for code re-use, which can drastically reduce code duplication if used correctly. Additionally, encapsulation, another core OOP concept, allows you to create code with the implementation hidden. Although, in many cases, writing OOP code in Java (and other OOP languages) can take longer than using a procedural language, the benefits obtained with OOP, namely code reusability, encapsulation of data, and readability of code, often result in code that is easier to maintain in the long run.What is Java used for?Java is a very versatile language. Several fields use Java, including Android app development, desktop applications that work on many operating systems, server-side applications, and more. The virtual machine required to run Java programs has been ported to numerous operating systems allowing Java to run on virtually all hardware. According to the TIOBE index, Java has consistently been in the top 3 most-used and popular languages since its initial release in the 1990s. Many developers still consider Java the language of choice in areas such as enterprise and application servers, and even in embedded systems development. Many Fortune 500 companies rely on Java to run their core systems and employers often view Java experience on a résumé as favorable due to its popularity.What certification is best for Java?Oracle, the owner of the Java programming language, has the Oracle Certified Developer: Java SE 21 Developer program, which is easily the best certification to obtain for Java developers. The main reason why it's the best certification, is, unlike most other certifications for Java, the Oracle certification is both well known and universally accepted by employers all over the world. The exam is challenging. You also must bring an ID with you to the exam, so you cannot get anyone to take it for you. Certification is really valuable for both the certification holder and for future employers. There are few, if any, other certification programs so universally accepted as Oracle's Java certification. Thus, getting Java certification is one of the surest ways to give yourself an advantage over other job seekers in the marketplace.Why would you want to take this course?Our answer is simple: The quality of teachingOAK Academy based in London is an online education company OAK Academy gives education in the field of IT, Software, Design, development in Turkish, English, Portuguese, and a lot of different language on Udemy platform where it has over 2000 hours of video education lessons.
