For a solution of managing different python versions, please look at https://www.baeldung.com/linux/python-multiple-versions.

5. create /opt/tools for other tools

sudo mkdir /opt/tools

6. install “j” in /opt/tools

sudo mkdir /opt/tools/j
sudo chown $USER /opt/tools/j
sudo cat > /opt/tools/j/j.sh << 'EOF'
#!/usr/bin/env bash

function print_usage() {
    VERSIONS=$(\ls $SDKMAN_DIR/candidates/java | \grep -v current | \awk -F'.' '{print $1}' | \sort -nr | \uniq)
    CURRENT=$(\basename $(\readlink $JAVA_HOME || \echo $JAVA_HOME) | \awk -F'.' '{print $1}')
    \echo "Available versions: "
    \echo "$VERSIONS"
    \echo "Current: $CURRENT"
    \echo "Usage: j <java_version>"
}

if [[ $# -eq 1 ]]; then
  VERSION_NUMBER=$1
  IDENTIFIER=$(\ls $SDKMAN_DIR/candidates/java | \grep -v current | \grep "^$VERSION_NUMBER." | \sort -r | \head -n 1)
  sdk use java $IDENTIFIER
else
  print_usage
fi
EOF
chmod u+x /opt/tools/j/j.sh
