Java Development Kit (JDK) 22 is the latest version of the Java Platform, offering new features and improvements for developers. This guide will walk you through the steps to install JDK 22 on an AlmaLinux 8.10 system.<\/p>\n\n\n\n
Before you begin, ensure you have:<\/p>\n\n\n\n
First, update your system to ensure all existing packages are up to date.<\/p>\n\n\n\n
$ sudo dnf update -y<\/code><\/pre>\n\n\n\nStep 2: Download JDK 22<\/h3>\n\n\n\n
Download the JDK 22 package from the official Oracle website. At the time of writing, JDK 22 is the latest version available.<\/p>\n\n\n\n
Visit the Oracle JDK Downloads page and download the RPM package. Alternatively, you can use the following command to download the RPM directly (replace the URL with the latest version if necessary):<\/p>\n\n\n\n
$ wget https:\/\/download.oracle.com\/java\/22\/latest\/jdk-22_linux-x64_bin.rpm<\/code><\/pre>\n\n\n\nStep 3: Install JDK 22<\/h3>\n\n\n\n
Install the downloaded JDK 22 RPM package using the dnf<\/code> package manager.<\/p>\n\n\n\n$ sudo dnf localinstall jdk-22_linux-x64_bin.rpm<\/code><\/pre>\n\n\n\nStep 4: Verify the Installation<\/h3>\n\n\n\n
To verify that JDK 22 has been installed correctly, check the Java version.<\/p>\n\n\n\n
$ java -version<\/code><\/pre>\n\n\n\nYou should see output similar to this, indicating the installed version of Java:<\/p>\n\n\n\n
java version "22"\nJava(TM) SE Runtime Environment (build 22+36-2345)\nJava HotSpot(TM) 64-Bit Server VM (build 22+36-2345, mixed mode)<\/code><\/pre>\n\n\n\nStep 5: Set Up Java Environment Variables<\/h3>\n\n\n\n
Setting up environment variables ensures that Java applications can find the JDK installation.<\/p>\n\n\n\n
Open Profile File<\/h4>\n\n\n\n
Open the profile file to add the environment variables.<\/p>\n\n\n\n
$ sudo nano \/etc\/profile.d\/jdk.sh<\/code><\/pre>\n\n\n\nAdd the Following Lines<\/h4>\n\n\n\n
Add the following lines to set up the JAVA_HOME environment variable and update the PATH.<\/p>\n\n\n\n
$ export JAVA_HOME=\/usr\/java\/jdk-22\n$ export PATH=$PATH:$JAVA_HOME\/bin<\/code><\/pre>\n\n\n\nApply the Changes<\/h4>\n\n\n\n
Save the file and apply the changes.<\/p>\n\n\n\n
$ source \/etc\/profile.d\/jdk.sh<\/code><\/pre>\n\n\n\nStep 6: Verify Environment Variables<\/h3>\n\n\n\n
To ensure the environment variables are set correctly, check the JAVA_HOME and PATH variables.<\/p>\n\n\n\n
$ echo $JAVA_HOME\n$ echo $PATH<\/code><\/pre>\n\n\n\nYou should see output that includes the path to your JDK 22 installation.<\/p>\n\n\n\n
Step 7: Test the Installation<\/h3>\n\n\n\n
Create a simple Java program to test your JDK installation.<\/p>\n\n\n\n
Create a Java Program<\/h4>\n\n\n\n
Create a file named HelloWorld.java<\/code>.<\/p>\n\n\n\n$ nano HelloWorld.java<\/code><\/pre>\n\n\n\nAdd the following content to the file:<\/p>\n\n\n\n
public class HelloWorld {\n public static void main(String[] args) {\n System.out.println("Hello, World!");\n }\n}<\/code><\/pre>\n\n\n\nCompile the Java Program<\/h4>\n\n\n\n
Compile the Java program using the javac<\/code> command.<\/p>\n\n\n\n$ javac HelloWorld.java<\/code><\/pre>\n\n\n\nRun the Java Program<\/h4>\n\n\n\n
Run the compiled Java program.<\/p>\n\n\n\n
$ java HelloWorld<\/code><\/pre>\n\n\n\nYou should see the output:<\/p>\n\n\n\n
Hello, World!<\/code><\/pre>\n\n\n\nConclusion<\/h3>\n\n\n\n
You have successfully installed JDK 22 on your AlmaLinux 8.10 system. Java is now ready for you to start developing robust and scalable applications. For more detailed information and advanced usage, refer to the official Java documentation<\/a>.<\/p>\n\n\n\nHappy coding!<\/p>\n\n\n\n
