$ sudo apt update\n$ sudo apt upgrade -y<\/code><\/pre>\n\n\n\n
Step 2: Install Java 22<\/h3>\n\n\n\n
Method 1: Using the Official Oracle JDK<\/h4>\n\n\n\n
\n
\n
$ sudo tar -xvzf jdk-22_linux-x64_bin.tar.gz -C \/opt<\/code><\/pre>\n\n\n\n
\n
$ sudo nano \/etc\/profile.d\/jdk22.sh<\/code><\/pre>\n\n\n\n
$ export JAVA_HOME=\/opt\/jdk-22\n$ export PATH=$PATH:$JAVA_HOME\/bin<\/code><\/pre>\n\n\n\n
$ sudo chmod +x \/etc\/profile.d\/jdk22.sh\n$ source \/etc\/profile.d\/jdk22.sh<\/code><\/pre>\n\n\n\n
\n
$ java -version<\/code><\/pre>\n\n\n\n
Method 2: Using OpenJDK (if available)<\/h4>\n\n\n\n
\n
$ sudo apt install -y openjdk-22-jdk<\/code><\/pre>\n\n\n\n
\n
$ java -version<\/code><\/pre>\n\n\n\n
Step 3: Set Up JAVA_HOME<\/h3>\n\n\n\n
JAVA_HOME<\/code> environment variable is important for some applications to find your Java installation.<\/p>\n\n\n\n
\n
$ sudo nano \/etc\/environment<\/code><\/pre>\n\n\n\n
\n
$ JAVA_HOME="\/usr\/lib\/jvm\/java-22-openjdk-amd64"<\/code><\/pre>\n\n\n\n
$ JAVA_HOME="\/opt\/jdk-22"<\/code><\/pre>\n\n\n\n
\n
$ source \/etc\/environment<\/code><\/pre>\n\n\n\n
Step 4: Verify the JAVA_HOME Variable<\/h3>\n\n\n\n
JAVA_HOME<\/code> variable is set correctly:<\/p>\n\n\n\n
$ echo $JAVA_HOME<\/code><\/pre>\n\n\n\n
Step 5: Set Java 22 as the Default Java Version<\/h3>\n\n\n\n
