Learn Hands-On Programming in Java

Java is a powerful general-purpose programming language. It is used to develop desktop and mobile applications, big data processing, embedded systems, and so on. According to Oracle, the company that owns JavaJava runs on 3 billion devices worldwide, which makes Java one of the most popular programming languages.

Java is an object-oriented, class-based, concurrent, secured and general-purpose computer-programming language. It is a widely used robust technology.

Java was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995. James Gosling is known as the father of Java. Before Java, its name was Oak. Since Oak was already a registered company, so James Gosling and his team changed the Oak name to Java.

Platform: Any hardware or software environment in which a program runs, is known as a platform. Since Java has a runtime environment (JRE) and API, it is called a platform.

Different Types of Java Applications

There are mainly 4 types of applications that can be created using Java programming:

  1. Standalone Application: These are traditional software that we need to install on every machine. They are also known as desktop applications or window-based applications
  2. Web Application: An application that runs on the server-side and creates a dynamic page is called a web application. Some technologies like Servlet, JSP, Struts, Spring, etc are used for creating web applications in Java.
  3. Enterprise Application: An application that is distributed in nature, such as banking applications, etc. is called an enterprise application. It has advantages of high-level security, load balancing, and clustering. EJB is used for creating enterprise applications.
  4. Mobile Application: An application that is created for mobile devices is called a mobile application. Currently, Android and Java ME are used for creating mobile applications.

First of all, I must say you cannot learn something like java or any programming language in one day. If you have any prior knowledge of any programming language you should already know that. But if you want to learn it really fast what you can do is start watching a series of online tutorials.
