It was released under a proprietary license by Sun Microsystems. In the year 2010, Oracle Corporation purchased Java from Sun Microsystems. Currently, Oracle is the owner of Java until today.<\/p>\n<p>Java works on the principle of Once <strong>Run Anywhere<\/strong> (WORA), which means you can write code in one platform and run it in multiple supported platforms. This is possible in Java because code written in Java is compiled to an intermediate result also known as \u2018bytecode\u2019 which is <strong>platform-independent<\/strong> i.e it can run on different platforms using a virtual machine known as <strong>Java Virtual Machine<\/strong> (JVM).<\/p>\n<p>Java runs on billions of devices and more than ten million developers have created Java applications around the world.<\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-164 size-large\" src=\"https:\/\/usemynotes.com\/wp-content\/uploads\/2020\/10\/java-platform-independent-1024x680.jpg\" alt=\"Platform Independent\" width=\"1024\" height=\"680\" title=\"\" srcset=\"https:\/\/usemynotes.com\/wp-content\/uploads\/2020\/10\/java-platform-independent-1024x680.jpg 1024w, https:\/\/usemynotes.com\/wp-content\/uploads\/2020\/10\/java-platform-independent-300x199.jpg 300w, https:\/\/usemynotes.com\/wp-content\/uploads\/2020\/10\/java-platform-independent-768x510.jpg 768w, https:\/\/usemynotes.com\/wp-content\/uploads\/2020\/10\/java-platform-independent-150x100.jpg 150w, https:\/\/usemynotes.com\/wp-content\/uploads\/2020\/10\/java-platform-independent-696x462.jpg 696w, https:\/\/usemynotes.com\/wp-content\/uploads\/2020\/10\/java-platform-independent-1068x709.jpg 1068w, https:\/\/usemynotes.com\/wp-content\/uploads\/2020\/10\/java-platform-independent-632x420.jpg 632w, https:\/\/usemynotes.com\/wp-content\/uploads\/2020\/10\/java-platform-independent.jpg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Important\"><\/span>Important:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li>Java and Javascript are two different programming languages that are confused with each other.<\/li>\n<li>Both Java and Javascript are different in nature and both have different working methodologies.<\/li>\n<li>Java is a computer programming language owned by Oracle Corporation.<\/li>\n<li>JavaScript is a scripting language that is an implementation of the ECMAScript language standard.<\/li>\n<\/ul>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Why_Should_I_learn_Java\"><\/span>Why Should I learn Java?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Easy_to_Learn\"><\/span>Easy to Learn<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Java is an easy to learn language. Java has a strong syntax and at the same time, it is an unambiguous programming language. If you are new to programming, then you might feel it a bit difficult in the beginning to grasp all the concepts but as you move forward it will all make sense to you. It has a bit of a learning curve initially but as you progress things get easy and really easy.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Java_is_Object-Oriented\"><\/span>Java is Object-Oriented<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Java is an object-oriented programming language. It supports object-oriented concepts like Polymorphism, Abstraction, Inheritance, Data hiding, etc. These concepts are very likely to be used when developing programming applications in a modular and reusable way. It provides security within modules as well.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Has_wide_Platform_Support\"><\/span>Has wide Platform Support<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Java is used in various platforms such as Windows, Linux, Mobile phones, Websites, Servers, FreeBSD, and many more. At this point, there might be some electronic gadgets around you that might be using Java right now. The device that you are using to read the contents right now is probably using Java.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Execution_Speed\"><\/span>Execution Speed<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Java is comparatively faster than other programming languages that are available in the market. Programs executed using Java programming language are faster because all you have to do is compile your programs to generate the bytecode and the rest is handled by JVM. The JVM converts the byte code to the machine-understandable code. This final executable code is faster in execution and doesn\u2019t need any further interpretation on the second run.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Popularity\"><\/span>Popularity<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Java is currently being used by more than 10 million developers across the world which makes it one of the most popular programming languages in the world.

Due to its feature of being platform-independent, it has grown so much that it is almost everywhere. Here are some of the key applications of Java:<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Mobile_Applications\"><\/span>Mobile Applications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Most of the smartphones that are available in the market are based on Java. The popular well known operating system Android OS is also based on Java.<\/p>\n<p>Java is also one of the languages that are widely used to create mobile applications. There are libraries and tools that come in-built with the software package known as Android Studio which has Java APIs available to create android applications for both personal and commercial purposes.<\/p>\n<p>There are mobile apps that we see in App stores are mostly built around Java. Developers prefer Java for their App development due to its rich features, toolset, and better documentation.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Desktop_Applications\"><\/span>Desktop Applications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Java has predefined libraries to develop a fully functioning Desktop application. It comes packed with prebuilt UI packages that can be used to create GUI applications. Packages like Abstract Window Toolkit (AWT), Java Swing, and other graphics media packages are available in Java. These are the tools and components that are basically required in a general desktop-based application. To make it easy for the developers, every component of the UI library available in Java is well documented as well as fully customizable according to the developer\u2019s style and needs. There are several external open-source UI libraries available across the Internet that may come in handy to extend the UI functionality of Java.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Web_Applications\"><\/span>Web Applications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Java is just not limited to Desktop or Mobile applications. It is also supported for the development of Web applications. It has great tools and components that are pretty much used to design any kind of backend server environment. Due to its top-class security features and high robustness, it is one of the preferred languages that are used in large-scale web development projects.<\/p>\n<p>Java Servlets, Java Server Pages (JSP), JavaFX, Spring MVC are a few key technologies that use Java for web development. These technologies are being updated frequently and new libraries are being added to enhance them for the long run.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Enterprise_Applications\"><\/span>Enterprise Applications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Enterprises and Corporate environments need large software solutions and technology stacks to operate, tackle, and solve their problems. Java EE platform is designed for developers to create large-scale, scalable, multi-tiered, reliable, and secure network applications. It covers essential features and functionality for not only large companies but also for government agencies and small organizations.<\/p>\n<p>Giant tech companies need robust, scalable, secure as well as powerful software solutions to perform their business operations and Java is capable of doing that. The Java EE package has development APIs that will make developers focus more on building solutions rather than focusing on code. This will only increase productivity but will also let developers create large-sized applications collaboratively.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Distributed_Applications\"><\/span>Distributed Applications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Java can operate on multiple servers at a time by its distributed computing nature\/feature. It can connect to multiple resources in a network to build a complex architecture to run software applications in a distributive way. These distributed network resources are also termed as Nodes that are connected to each other and work together to fulfil a goal or need. Its main use can be mostly seen in enterprise-level applications.<\/p>\n<p>Java Provides APIs to develop distributed applications. Java Intelligent Network Infrastructure (JINI) is a network operating system built on Java that is popularly known for distributed application development.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Scientific_Applications\"><\/span>Scientific Applications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Scientific research and scientific calculation are no longer difficult to perform when you have Java on your side. Java is filled with libraries that support both mathematical and scientific calculations. It has a very good accuracy of results when a large amount of calculations is thrown at it. From UI designing of scientific applications to output assembling everything is handled by the language.<\/p>\n<p>One of the well known mathematical libraries known as MatLab is also based on Java.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Embedded_Systems\"><\/span>Embedded Systems<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Most of today\u2019s embedded systems like Television, DVD player, Microwave Oven, Multimedia\/Music Player, etc. in one or the other way use Java in its core. Even some old keypad phones that were used (also being used currently) are powered by Java.<\/p>\n<p>Embedded Systems are coming assembled with low memory and processing power. Java still works efficiently in these types of systems by managing memory and processing power together. Its compiled programs are so small that it hardly takes any space in these embedded systems.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Big_Data\"><\/span>Big Data<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Data stored in the cloud is growing exponentially every single day. Companies collect these data to analyze trends and extract patterns to make critical decisions. Java is used in the development of such applications which can process large amounts of data to extract useful information based on which they can make critical decisions.<\/p>\n<p>Some known popular frameworks include Apache Spark and Apache Hadoop. Both of these technologies are used in big data processing and analysis.
