Easily select java version and distribution with sdkman

sdk-java.sh

#!/bin/bash
function sdkj() {
  if [ "$1" == "" ]; then
    echo "Expected Version prefix"
    exit 1
  fi
  PREFIX=$1
  CONTAINS=$2
  # list candidates in the order they were installed. Last matching installed will be selected.
  CANDIDATES=$(ls -tr ~/.sdkman/candidates/java/)
  CANDIDATE=
  for v in $CANDIDATES; do
    if [[ "$v" == *"${PREFIX}."* ]]; then
      if [ "$CONTAINS" != "" ]; then
          if [[ "$v" == *"${CONTAINS}"* ]]; then
            CANDIDATE="$v"
          fi
      else
        CANDIDATE="$v"
      fi
    fi
  done
  if [ "$CANDIDATE" != "" ]; then
    source "$HOME/.sdkman/bin/sdkman-init.sh"
    sdk use java $CANDIDATE
  else
    echo "Couldn't find an installed distribution for $@"    
  fi
}

if [ "$1" != "" ]; then
  sdkj $@
fi

Using it is as simple as:
source sdk-java.sh 17
OR
source sdk-java.sh 21 crac
OR
After source sdk-java.sh
sdkj 17
OR
sdkj 21 graal

Since semantic version don't sort in alphabetical order, updated to select the match that was installed last.
