阿琛1/19/24Less than 1 minuteLinuxJavaubuntu

Two ways to install JDK on Ubuntu (Nanny-level tutorial, spoon-feeding)

I. Upload the compressed package, extract, and configure

  1. Download the corresponding JDK package
https://www.openlogic.com/openjdk-downloads
  1. Extract
tar xzf openlogic-openjdk-17.0.9+9-linux-x64.tar.gz
  1. Modify environment variables with vim
cd /etc
cp  /etc/profile /home/vbox/temp/
cd /home/vbox/temp/
vim profile
# press i to edit

export JAVA_HOME=/home/vbox/java/openlogic-openjdk-17.0.9+9-linux-x64
export PATH=$PATH:$JAVA_HOME/bin

  1. Execute the source /etc/profile command to make the modifications take effect immediately

  2. To uninstall, you only need to delete the environment variables, and you can choose to delete the extracted folder.

II. Quick Installation

  1. Install
# Install JRE
sudo apt-get -y install openjdk-17-jre

# Install JDK
sudo apt-get -y install openjdk-17-jdk-headless
  1. Uninstall
 apt-get purge openjdk*

 apt-get purge icedtea-* openjdk-*

 dpkg --list | grep -i jdk        (If dpkg --list | grep -i jdk is empty, the uninstallation is complete)
