What is Java?
Java is a popular programming language that is used to develop a wide range of applications, including web applications, mobile applications, and games. It is a class-based, object-oriented language that is designed to be simple, easy to learn, and easy to write, compile, and debug.
One of the main features of Java is its “write once, run anywhere” (WORA) capability, which means that Java programs can run on any device that has a Java Virtual Machine (JVM) installed. This makes it a good choice for developers who want to create applications that can be easily deployed on multiple platforms.
Java is used by a large number of companies and organizations around the world, and it is a popular choice for developing enterprise applications, particularly for web applications. It is also used for developing Android mobile applications, as Android uses the Java programming language and the Android operating system includes a JVM.
How to Install Java on Debian Linux
To install Java on a Debian-based Linux distribution such as Ubuntu or Linux Mint, you can use the
apt package manager. There are two main ways to install Java on Debian:
Install the default OpenJDK package:
sudo apt update sudo apt install default-jdk
This will install the default version of OpenJDK, which is an open-source implementation of the Java platform.
Install the Oracle Java Development Kit (JDK) package:
sudo apt update sudo apt install oracle-java11-installer
This will install the Oracle JDK, which is the official Oracle version of the Java platform.
Once the installation is complete, you can verify that Java is installed and working correctly by running the
java -version command. This will display the version of Java that is currently installed on your system.
