My Raspberry Pi 3 came with Java version 1.8.0_65 installed. I could not update it to a later version using apt-get - I assume there's no Debian repo for it. I do not know how to update it, and installing a newer version does not replace the existing one.

What's the bet way to install/update Java on Raspbian, and keep it updated going forward?

To have all the time the most recent Oracle java installed, you can do check current Java

pi@raspberrypi:~ $ java -version java version "1.8.0_65" Java(TM) SE Runtime Environment (build 1.8.0_65-b17) Java HotSpot(TM) Client VM (build 25.65-b01, mixed mode)

remove OpenJDK 

sudo apt-get purge openjdk*

add digital key

sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com EEA14886

add packet source

sudo vim /etc/apt/sources.list

add following lines 

deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main
deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main

install Java 8

sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo apt-get install oracle-java8-set-default

remove old Java

sudo apt-get purge openjdk*
sudo apt-get purge java7*
sudo apt-get autoremove

check success

java -version

pi@raspberrypi:~ $ java -version java version "1.8.0_131" Java(TM) SE Runtime Environment (build 1.8.0_131-b11) Java HotSpot(TM) Client VM (build 25.131-b11, mixed mode)

The following advice by hannes ach and SWilk was successful, but I got the following error:

pi@raspberrypi:~ $ sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com C2518248EEA14886 
Executing: /tmp/apt-key-gpghome.hVyJ3FPvDb/gpg.1.sh --recv-keys --keyserver keyserver.ubuntu.com C2518248EEA14886 
gpg: failed to start the dirmngr '/usr/bin/dirmngr': No such file or directory 
gpg: connecting dirmngr at '/tmp/apt-key-gpghome.hVyJ3FPvDb/S.dirmngr' failed: No such file or directory 
gpg: keyserver receive failed: No dirmngr

In order to resolve that, I ran:

sudo apt-get install dirmngr --install-recommends

then

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com C2518248EEA14886

Then, everything worked as expected.

If you want new features now it's possible to get version 9 and 10 like this:

wget https://github.com/bell-sw/Liberica/releases/download/10/bellsoft-jre10-linux-arm32-vfp-hflt.debsudo
apt install ./bellsoft-jre10-linux-arm32-vfp-hflt.deb

Have you tried this guide yet? http://elinux.org/RPi_Java#Installing_Java_on_Raspberry_Pi

OpenJDK

sudo apt-get update
sudo apt-get install openjdk-7-jdk

Oracle Java 8

wget http://www.java.net/download/JavaFXarm/jdk-8-ea-b36e-linux-arm-hflt-29_nov_2012.tar.gz
tar zxf jdk-8-ea-b36e-linux-arm-hflt-29_nov_2012.tar.gz
rm jdk-8-ea-b36e-linux-arm-hflt-29_nov_2012.tar.gz
sudo mv ./jdk1.8.0/ /opt/
sudo chown root:root -R /opt/jdk1.8.0/
sudo ln -s /opt/jdk1.8.0/ /opt/jdk8

Edit sudo nano -w /etc/profile and add

PATH="$PATH":/opt/jdk8/bin
JAVA_HOME=/opt/jdk8

java -version

to see if java is working
