extract part of grep line using regex

I'm using the following command to get java.home path

java -XshowSettings:properties -version 2>&1 > /dev/null | grep 'java.home'

the command above returns

java.home = /usr/lib/jvm/java-11-openjdk-amd64

How can I get it to only return "/usr/lib/jvm/java-11-openjdk-amd64"

Just use awk to cut out the last field:

java -XshowSettings:properties -version 2>&1 >/dev/null | grep 'java.home' | awk '{print $NF}'

Or a little shorter:

java -XshowSettings:properties -version 2>&1 | awk '/java.home/ {print $NF}'
