In this article, we will explain how to install Java on Linux Mint.
1. Introduction
Java is the most popular programming language of all due to its platform independence nature and versatile features such as OOPS, Multi-threading, Multitasking, concurrent programming, and many more. In this tutorial, we are going to see how we can install Java on the Linux Mint flavor of OS. Hence if you are having a Linux Mint version installed in your computer you could go through the following steps to install Java in it and make it ready for all types of Java programming. Java comes in 3 different editions i.e.
- Java Standard Edition(J2SE)
- Java Enterprise Edition(J2EE)
- Java Micro edition(J2ME)
Moreover it is available in 2 diffferent implementations i.e.
- Open JDK: This is the open-source implementation of Java and does not require any license to use.
- Oracle JDK: This is the implementation of Java distributed by Oracle and requires license for its commercial use.
Before we install Java, we should also be familiar with the following two terms in context to the Java Technology :
- Java Development Kit(JDK): It is a software having all the Java APIs that would be required to write Java code in your system.
- Java Runtime Environment(JRE): It is a run time environment that enables us to run/execute programs written in Java successfully in our system.
2. Prerequisite
You should have a non-root user account in your Linux mint System with Sudo privileges before proceeding with the installation.
