I downloaded jdk-8u221-linux-x64.tar.gz
sudo mkdir /usr/local/java
cp jdk-8u221-linux-x64.tar.gz /usr/local/java
cd /usr/local/java
sudo tar xvf jdk-8u221-linux-x64.tar.gz
sudo rm jdk-8u221-linux-x64.tar.gz
sudo gedit ~/.bashrc
Add at the end after opening
export JAVA_HOME=/usr/local/java/jdk1.8.0_221
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
java -version
If something goes wrong
The program'java' has been included in the following packages:
default-jre
gcj-4.8-jre-headless
openjdk-7-jre-headless
gcj-4.6-jre-headless
openjdk-6-jre-headless
Please try: sudo apt-get install <selected package>
Terminal input
sudo update-alternatives --install /usr/bin/java java /usr/local/java/jdk1.8.0_221/bin/java 300
sudo update-alternatives --install /usr/bin/java java /usr/local/java/jdk1.8.0_221/bin/javac 300
sudo update-alternatives --config java
Enter java -version again in the terminal to display the version installed successfully
