locate java

This will give you the location of java installation in your system.

Most probably it would be:

/usr/lib/java/

Check your $JAVA_HOME environment variable from a terminal:

echo $JAVA_HOME

In linux you can use the whereis and which shell commands.

which java
whereis java

which will give you the jre path in /usr/bin folder which will be /usr/bin/java most probably. This is not the actual jre file but it's just a symbolic link to the actual jre file which is located else where. To know the actual jre path you will have to write

readlink -f /usr/bin/java

or whatever was the path of jre returned by which/whereis command.

which java

This is the simplest command and gives the exact path.

    This answer is not correct because it shows the path of the java binary, which will most likely be /usr/bin/java or something of that sort, which is different from the actual path of the JRE.
