Install 32-bit version of java8 on ubuntu 18 64-bit by apt command

I found this solution for similar question:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

I can't comment on the original post. My question is, does this procedure install the 64 or the 32-bit version of Java? If, as I suppose, it installs the 64bit version, is there a way to install the 32-bit version?

-------update-----

I tried to look by apt for a bundle 386 (on my ubuntu 18 64-bit) but I did not find it.

I also tried to install manually but it does not work.

I downloaded 32bit version and untar in /opt/java and if I enter the /opt/java/jdk1.8.0_181/bin directory and try to execute the java -version command I get the error -bash: /usr/bin/ java: No such file or directory.

in /usr/bin i have:

lrwxrwxrwx 1 root root 22 Sep 27 15:51 java -> /etc/alternatives/java*
lrwxrwxrwx 1 root root 23 Sep 27 15:51 javac -> /etc/alternatives/javac*

and in /etc/alternative/:

lrwxrwxrwx 1 root root 31 Sep 27 15:51 java -> /opt/java/jdk1.8.0_181/bin/java*
lrwxrwxrwx 1 root root 32 Sep 27 15:51 javac -> /opt/java/jdk1.8.0_181/bin/javac*

Try with apt show oracle-java8-installer. Also if you want to specify the architecture append it like:

apt install postgresql-10:i386

I would suggest to download and install java binary from: Java Downloads for Linux.
