Java is one of the most popular programming languages. This tutorial helps you learn about programming fundamentals and core concepts, such as loops, functions, and classes, and learn how to use them to create programs in Java. Along the way, we will be using real-world examples. Let’s get started learning Java.
What is Java?
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
Java can be used to create applications on the web, mobile, desktop, and many other platforms. Because of this, companies want to hire Java developers, and they are some of the most well-paid people in the industry. Do you want to learn how to code with Java? If so, this is the tutorial is for you.
Java is a very commonly used programming language, and it is often the first language beginners learn. When we say “programming language,” we do mean that it is an actual language, but we use it to talk to a computer. Just like a regular language, it has a vocabulary and a set of grammatical rules, so that it can communicate with the computer to complete certain tasks. With the Java programming language, software developers can create applications on a computer.
What types of applications we can create using java?
Web applications, mobile applications, desktop applications, web servers, embedded systems, and more. We call these applications Java programs because they are built with the Java programming language.
Requirement to learn Java
Chances are you’ve downloaded a program that requires the JRE, or Java Runtime Environment. This is what’s needed to run Java programs.
So what’s needed to build and develop a Java program?
You need to install the JDK, or Java Development Kit. The Java Development Kit is a full-featured software development kit that includes everything from the JRE, as well as compilers, debuggers, and tools to create Java programs. This means we can just install the JDK, or Java Development Kit, and we get the JRE, or Java Runtime Environment, automatically. So let’s get the JDK installed.
Downloading Java on your computer
Let’s install the Java Development Kit, or JDK so that we can build Java applications on our computer. Remember, the JDK includes the JRE, or Java Runtime Environment, so we will not only be able to build applications on our computer, but we will also be able to run them.
SE stands for Standard Edition, which is what we want, Here is the link to download: https://www.oracle.com/in/java/technologies/javase-downloads.html
With the JDK or Java Development Kit installed, we can now build and run Java programs.
