I have a Linux box on which Java 1.7 is installed:

But for some new tool I need to install the jdk-8u45-linux-x64.tar.gz

  1. To remove OpenJDK (the one you've already installed)

    sudo apt-get purge openjdk-* Marvell yukon 88e8059 windows 10.

  2. Make a new directory for your new JDK

    sudo mkdir -p /usr/local/java

  3. Copy the file to the directory (you should be in that file path)

    sudo cp -r jdk-8u45-linux-x64.tar.gz /usr/local/java/

  4. Extract the file

    sudo tar xvzf jdk-8u45-linux-x64.tar.gz

  5. You should add this to your PATH now. To do that:

    a. Open /etc/profile : sudo gedit /etc/profile

    It is now time to test it! It is very simple and I hoped that it will be reliable. Isp programmer software.

    b. Scroll down (the end) and add the path where your jdk was installed

    JAVA_HOME=/usr/local/java/jdk1.8.0_45PATH=$PATH:$HOME/bin:$JAVA_HOME/binexport JAVA_HOMEexport PATH

    Save and exit

  6. Inform your Linux system where your Oracle Java JDK/JRE is located.

    a. Notify the system that Oracle Java JRE is available for use

    sudo update-alternatives --install '/usr/bin/java' 'java' '/usr/local/java/jdk1.8.0_45/bin/java' 1

    b. Notify the system that Oracle Java JDK is available for use

    sudo update-alternatives --install '/usr/bin/javac' 'javac' '/usr/local/java/jdk1.8.0_45/bin/javac' 1

    c. Notify the system that Oracle Java Web start is available for use

    sudo update-alternatives --install '/usr/bin/javaws' 'javaws' '/usr/local/java/jdk1.8.0_20/bin/javaws' 1

  7. Inform your Linux system that Oracle Java JDK/JRE must be the default Java.

    a. Set the java runtime environment for the system

    sudo update-alternatives --set java /usr/local/java/jdk1.8.0_45/bin/java

    b. Set the javac compiler for the system

    sudo update-alternatives --set javac /usr/local/java/jdk1.8.0_45/bin/javac

    c. Set Java Web start for the system

    sudo update-alternatives --set javaws /usr/local/java/jdk1.8.0_20/bin/javaws

  8. Reload your system wide PATH

    Canoscan lide 700f user manual user. source /etc/profile

  9. Check the new version and you're done!

    java -version
