Java is a widely used object-oriented programming language and software platform that runs on billions of devices, including notebook computers, mobile devices, gaming consoles, medical devices and many others. The rules and syntax of Java are based on the C and C++ languages. One major advantage of developing software with Java is its portability. Once you have written code for a Java program on a notebook computer, it is very easy to move the code to a mobile device. When the language was invented in 1991 by James Gosling of Sun Microsystems (later acquired by Oracle), the primary goal was to be able to "write once, run anywhere." It's also important to understand that Java is much different from JavaScript. Javascript does not need to be compiled, while Java code does need to be compiled. Also, Javascript only runs on web browsers while Java can be run anywhere. New and improved software development tools are coming to market at a remarkable pace, displacing incumbent products once thought to be indispensable. In light of this continual turnover, Java’s longevity is impressive; more than two decades after its creation, Java is still the most popular language for application software development—developers continue to choose it over languages such as Python, Ruby, PHP, Swift, C++, and others. As a result, Java remains an important requirement for competing in the job market. IBM offers a simple tutorial to learn Java for Before exploring the reasons for Java’s enduring p...

What is Java? Java is a popular programming language, created in 1995. It is owned by Oracle, and more than 3 billion devices run Java. It is used for: • Mobile applications (specially Android apps) • Desktop applications • Web applications • Web servers and application servers • Games • Database connection • And much, much more! Why Use Java? • Java works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.) • It is one of the most popular programming language in the world • It has a large demand in the current job market • It is easy to learn and simple to use • It is open-source and free • It is secure, fast and powerful • It has a huge community support (tens of millions of developers) • Java is an object oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs • As Java is close to Get Started It is not necessary to have any prior programming experience.

What is Java? Java is a most popular, object-oriented, widely used programming language and platform that is utilized for Android development, web development, artificial intelligence, cloud applications, and much more. So, mastering this gives you great opportunities in bigger organizations. Simple Hello World Program : • • • • Features of Java Java is one of the most popular and widely used programming languages. • Java has been one of the most popular programming languages for many years. • Java is Object Oriented. However, it is not considered as pure object-oriented as it provides support for primitive data types (like int, char, etc) • The Java codes are first compiled into byte code (machine-independent code). Then the byte code runs on Java Virtual Machine (JVM) regardless of the underlying architecture. • Java syntax is similar to C/C++. But Java does not provide low-level programming functionalities like pointers. Also, Java codes are always written in the form of classes and objects. • Java is used in all kinds of applications like Mobile Applications (Android is Java-based), desktop applications, web applications, client-server applications, enterprise applications, and many more. • When compared with C++, Java codes are generally more maintainable because Java does not allow many things which may lead to bad/inefficient programming if used incorrectly. For example, non-primitives are always references in Java. So we cannot pass large objects (like we can do in...
