printjavahome

How to use

switch both java path and JAVA_HOME env at once

# switch java path
sudo alternatives --config java

# set JAVA_HOME
JAVA_HOME=$(java -jar printjavahome.jar)
export JAVA_HOME

echo "JAVA_HOME=${JAVA_HOME}"
echo ""

or set an alias in .bashrc

alias setjavahome='JAVA_HOME=$(java -jar printjavahome.jar) && export JAVA_HOME'

which is equivalent to

alias setjavahome='JAVA_HOME=$(readlink -f $(which java) | sed s/\\/bin\\/java$//) && export JAVA_HOME'

You can run PrintJavaHome.java without compilation with JDK 11+

$ java src/main/java/com/github/tkote/javahome/PrintJavaHome.java

There is a jshell version

$ $JAVA_HOME/bin/jshell printjavahome.jsh
