This course is designed for professionals aspiring to become: - • Java Developers • Programmers • Web Developers • Web Designers • Programming Hobbyists • Database Administrators • Youngsters who want to kick-start their career are the key beneficiaries of this course. ----------------------------------------------------------------------- Why learn Java? Java is a general-purpose, class-based, object-oriented computer programming language that was designed by James Gosling at Sun Microsystems in 1995. Key Highlights of Java: Platform Independent: This allows programmers to develop applications that can run on any operating system. Usability of Java: Java is most widely used programming language. It is present everywhere. It really doesn't matter which domain you are working in, you will surely come across Java sooner or later! Open Source: The good news is that Java is available for free! All the development tools and the environment (JRE & JDK) that is used to develop Java applications are absolutely free of cost. Android: Irrespective of the fact that you are tech savvy or not, most of us are badly bitten by the Android bug! Android is in great demand today and fortunately you need Java for Android development. Hence, the importance of Java has increased even more. Hadoop: Hadoop is one of the most trending framework for processing Big Data. It has been designed and developed in Java. Despite having a tough competition on the server side from Microsoft and other companies, Java is doing extremely well on mobile platforms, thanks to Android! It has also been the primary language for Hadoop Developers.
