Even though OpenJDK is available in Linux repositories, some applications strictly require Oracle Java Development Kit. This article shows you how to manually install Oracle JDK 11 on your Linux system. This article uses JDK 11$java_update_no to demonstrate the installation. In the provided commands, replace the version specific paths and file names according to your downloaded version.
Oracle JDK 12 has been released
To install the latest Oracle JDK, please visit Install the latest Oracle JDK on Linux.
Step 1:
Download the latest JDK(jdk-11$java_update_no_linux-x64_bin.tar.gz) from the official site.
If you want to download to a remote server or if you simply prefer wget, use the command given in this StackOverflow answer: Downloading JDK

Step 2:
Open the terminal (Ctrl + Alt + T) and enter the following command.
sudo mkdir /usr/lib/jvmIf the /usr/lib/jvm folder does not exist, this command will create the directory. If you already have this folder, you can ignore this step and move to the next step.
Step 3:Enter the following command to change the directory.
cd /usr/lib/jvmStep 4:
Extract the jdk-Xuxx-linux-xXX.tar.gz file in that directory using this command.
sudo tar -xvzf ~/Downloads/jdk-11$java_update_no_linux-x64_bin.tar.gzStep 5:
Enter the following command to open the environment variables file.
sudo nano /etc/environmentAccording to your personal preference, you can choose any text editors instead of nano.
Step 6:
In the opened file, add the following bin folder to the existing PATH variable.
/usr/lib/jvm/$java_version/binAdd the following environment variables at the end of the file.
JAVA_HOME="/usr/lib/jvm/$java_version"The environment file before the modification:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"The environment file after the modification:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/$java_version/bin"
JAVA_HOME="/usr/lib/jvm/$java_version"Save the changes and close nano (Ctrl + O, Ctrl + X).
Step 7:
Enter the following commands to inform the Ubuntu about the Java's location. Depending on your JDK version, the paths can be different.
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/$java_version/bin/java" 0sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/$java_version/bin/javac" 0sudo update-alternatives --set java /usr/lib/jvm/$java_version/bin/javasudo update-alternatives --set javac /usr/lib/jvm/$java_version/bin/javacStep 8:
To verify the setup enter the following commands and make sure that they print the location of java and javac as you have provided in the previous step.
update-alternatives --list javaupdate-alternatives --list javacStep 9:
Restart the computer (or just log-out and login) and open the terminal again.
Step 10:
Step 10:
Enter the following command.
java -versionIf you get the installed Java version as the output, you have successfully installed the Oracle JDK in your system.

Did you follow Step 7 and made sure the correct Java is selected in Step 8? If so, please check your operating system architecture. It should be 64 bit to install 64bit Java.
ReplyWorked perfectly for me. Thanks! :)
Replythank's it works....
ReplyHello,
ReplyI followed your instructions and worked perfect. Except I have a few questions. Before looking at this article I installed the openjdk version. I am saying this because when I look the path of other java tools (eg. jar, jarsigner) it traced back to the openjdk folder. I want to know, in the future, are there gonna be any problem with this? Of course in case I use these tools.
I don't know if I explained myself clear enough ':-).
Hi,
ReplyThere is nothing wrong with having OpenJDK. /usr/lib/jvm is used as the parent for all JDK installations. Suppose you also installed Oracle JDK 8, you will find it in the same folder. I don't find any issues with using tools from both Oracle JDK and Open JDK. You are fine with your current setup.
Thanks!!
ReplyI have jdk8 .0.212 installed in my Ubuntu PC, can I install another version of jdk like jdk11 this way?
ReplyYes you can but if you prefer to use JDK 8 as the default JDK, do not follow step 5-10.
ReplyHi, I've follow the tutorial until step 7, but, when i run the first command, this appears: update-alternatives: error: alternative path /usr/lib/jvm/jdk-11/bin/java doesn't exist
ReplyI don't know whats wrong.
Hi, Please share the output of the following command:
Replyls /usr/lib/jvm
Hey Laura,
ReplyIt looks like you are running the command exactly as the OP is.
He was using version 11, but if you are using the latest version, in my case it was 12.0.1, you will have to use the version that you have. So in my case, instead of using:
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk-11/bin/java" 0
I had to write:
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk-12.0.1/bin/java" 0
So figure out exactly what version you have (you can know if you run the command Gobinath mentioned) and replace 'jdk-11' with your version. (Ex: jdk-12.0.1)
