How to upgrade Java on Ubuntu?

I installed Ubuntu on my computer, and now my Java version is not updated. I have Java, so I don’t need to install — just update the current version. Can someone please tell me the command I have to use to get the current version? I have tried: apt-get update and apt-get upgrade .

Note: WebUpd8 team’s PPA has been discontinued with effective from April 16, 2019. Thus this PPA doesn’t have any Java files. More information can be found on PPA’s page on Launchpad. Hence this method no longer works and exists because of historical reasons.

sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer 

sudo apt-get install oracle-java8-installer 

If you ABSOLUTELY need to have the latest update of java you must manualy install from official source, follow this tuto : http://www.cyberciti.biz/faq/howto-installing-oracle-java7-on-ubuntu-linux/

But I advise you to wait as ppa update

I tried this one but it will not install the newest version. I have checked it out on java-website. I have now version 7 update 65 and I want version 7 update 67.

root@ubuntu:/home/kenneth# sudo apt-get install oracle-java7-installer Reading package lists. Done Building dependency tree Reading state information. Done oracle-java7-installer is already the newest version. 0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.

Found something useful here..

Installing Java with apt-get is easy. First, update the package index:

Check if Java is not already installed:

 sudo apt-get install default-jre sudo apt-get install default-jdk 

This worked great for me in March 2016. my system is always fairly up-to-date so just the last two commands (the install s) did it for up

Note: WebUpd8 team’s PPA has been discontinued with effective from April 16, 2019. Thus this PPA doesn’t have any Java files. More information can be found on PPA’s page on Launchpad. Hence this method no longer works and exists because of historical reasons.

The newest OpenJDK Java packaged for trusty (14.04) right now is 7u55. You can check your Java version with java -version from the command line in Terminal.

If you want a newer one your best options will be to:

• wait for an update from Ubuntu, OR
• install the Oracle distribution of Java which currently is at 7u65:

sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer

How to Upgrade Java on Ubuntu?

Java is a high-level, object-oriented programming language that is widely used for developing desktop, mobile, and web applications. Java, like other applications, offers updated versions regularly. If your system or any programs are Java-dependent, then it is necessary to keep the Java version updated to get the latest features and support.

This post will address the possible methods to upgrade Java on Ubuntu:

Method 1: Using Apt Package Manager to Upgrade Java on Ubuntu

The most common method is to use the “APT” package manager, which allows users to easily upgrade to the latest version of Java by running a few commands in the terminal.

Step 1: Check the Existing Java Version

To check the installed java version in the operating system, run the “java” command with the “version” option:

The output shows that currently, the “1.8.0_352” version of Java is installed in the system.

Step 2: Update the Package Manager

To update the package manager’s list, use the “apt” command with the “update” utility in the following command:

The output shows that the package manager has been updated.

Install the Latest Version (Upgraded)

To install the latest version of OpenJDK, use the “APT” package manager by specifying the “openjdk-19-jdk” command:

$ sudo apt install openjdk-19-jdk

The output shows that the latest version of Java 19 along with dependent files have been installed in the system.

Note: Users can also utilize the “sudo apt upgrade” command to upgrade all installed packages, including Java, in the current system. In addition, Java 19 is the extended version of the Java 17 LTS version.

Verify the Upgraded Java Version

To verify the installed version of Java, specify the “java” command with the “version” option as below:

This command displays the “19.0.1” version of Java that is upgraded on the system.

Method 2: Using the .deb File to Upgrade Java (Manually)

To upgrade Java manually, download the latest version of Oracle JDK from the Official Website and install it on the Ubuntu system. Follow these steps to do this:

Step 1: Download the Latest JDK Version

Go to the Oracle JDK download page and download the upgraded version of the .deb file for Linux:

$ sudo wget https://download.oracle.com/java/19/latest/jdk-19_linux-x64_bin.deb

The output shows that the latest version of the .deb file has been downloaded in the system.

Note: Go to the Official Website to have the latest available “.deb” version of Java.

Step 2: Install the Latest Version of OpenJDK

To upgrade Java on Ubuntu, use the .deb package file to install the most recent version of OpenJDK:

$ sudo apt install ./jdk-19_linux-x64_bin.deb

In this way, all dependencies with the latest version of java are installed in the system.

Step 3: Verify Upgraded Version of Java

To verify the upgraded version of Java, utilize the “version” option with the “java” command:

It displays the “19.0.1” version of Java that is currently installed on the system.

Conclusion

To upgrade Java on Ubuntu, use the “$ sudo apt install openjdk-19-jdk” command or download the latest version of Java from the Oracle Website and install it manually on the system. After the upgrade, execute the “java -version” to confirm the installed version of Java.
