How to Install Java on Linux

Installing Java on Linux is a straightforward process that can be completed in a few simple steps. Java is a widely-used programming language and platform, and it is essential for running applications that require Java. Whether you are a developer or a user, knowing how to install Java on your Linux system is a valuable skill.

Step 1: Check if Java is already installed

Before installing Java, it’s a good idea to check if it is already installed on your system. You can do this by opening a terminal and typing the following command:

“`
java -version
“`

If Java is already installed, the command will display the version of Java that is currently installed. If the command is not found, it means that Java is not installed on your system.

Step 2: Download Java from the official website

Go to the official Oracle Java website (er=221886 and download the Java package that is compatible with your Linux distribution. For most Linux distributions, you will need to download the Java Runtime Environment (JRE) or Java Development Kit (JDK) package.

Step 3: Install Java on your Linux system

Once you have downloaded the Java package, you can install it on your Linux system using the following steps:

For Ubuntu:

“`
sudo dpkg -i jdk--linux-x64.tar.gz
“`

For CentOS:

“`
sudo yum install -y java-1.8.0-openjdk
“`

For Fedora:

“`
sudo dnf install -y java-1.8.0-openjdk
“`

Replace `` with the actual version number of the Java package you downloaded.

Step 4: Verify Java installation

After installing Java, you should verify that it has been installed correctly by running the following command in the terminal:

“`
java -version
“`

This command should now display the version of Java that you installed. If the command is successful, Java has been installed on your Linux system.

Step 5: Set Java as the default JDK

In some cases, you may have multiple Java versions installed on your system. To set the default Java version, you can use the `update-alternatives` command:

“`
sudo update-alternatives –install /usr/bin/java java /usr/lib/jvm/jdk-/bin/java 1
sudo update-alternatives –config java
“`

Replace `` with the version number of the Java JDK you want to set as the default. You will then be prompted to select the default Java version from a list.
