Can `apt-get install` be used for JDK?

Question

I've been using a linux machine for less than two weeks, so I am extremely new to Linux.

I'd also like to install the Java Developers Kit. How should this be done? Is there an apt-get command, or should I just click on the download button at Sun's website?

I'm sure there is more than one way to do this, and it probably doesn't matter much, but I was impressed with how smoothly apt-get install worked when installing PHP and MySQL, so if there is a right way to do this, I'd like to know.

I'm using Ubuntu version 9.04

The Oracle JDK is no longer included in the Ubuntu repos. According to https://stackoverflow.com/a/15543636/192221 , the following ppa can be used:

echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" | tee -a /etc/apt/sources.list
echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" | tee -a /etc/apt/sources.list
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886
apt-get update
apt-get install oracle-java7-installer

If you have OpenJDK installed already, you might need to use

update-alternatives --config java

to use the Oracle Java by default.

Yes, definitely it's the suggested way to install JDK on your Linux system (if available).

On Ubuntu:

sudo apt-get install sun-java6-jdk

Solution 3

If you for some reason need to install the sun packages you can use the make-jpkg command to create a deb file and still have the files managed by apt/dpkg.

To do this:

sudo apt-get install java-package
fakeroot make-jpkg jre-1_5_0_06-linux-i586.bin

you will then have a .dpg file that you can install using for example gdebi

gdebi-gtk jre.deb

Also note that you can have multiple JDKs installed and switch between them using update-alternatives:

update-alternatives --config java
update-alternatives --config javac

and so on for other java related binaries, have a look in /etc/alternatives to find out which are available.

My Ubuntu box has sun-java5-jdk and sun-java6-jdk available.

Solution 5

I am personally a linux mint person. However, I couldn't find this in my respitory:

sudo apt-get install sun-java6-jdk

After poking around for a bit, I was able to get this to work.

sudo apt-get install openjdk-6-jdk

Cheers.

That's not true anymore, nor for Oracle JDK 6 or 7.
