[guide] Install java 7 on Debian-based systems

[llbranco]

A quick how-to install Oracle’s JAVA 7 on Debian 7 or based (including Debian 7 kfreebsd)

 

First make sure the system is up-to-date:

apt-get update
apt-get upgrade
apt-get dist-upgrade

 

must to be root or sudo

(if you isn't root use sudo before each command, like "sudo apt-get update")

 

first, edit your source.list 

nano /etc/apt/source.list

 

add this lines on the end of file:

#sid
deb http://cdn.debian.net/debian/ sid main non-free contrib
deb-src http://cdn.debian.net/debian/ sid main non-free contrib

 

then update your apt and install java7 (jre and jdk)

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

 

 

edit your source.list 

nano /etc/apt/source.list

 

comment or remove this lines on the end of file:

(or your system can be updated to somekind of unstable/beta)

(f you want to use Debian Sid (the beta/unstable version) keep it)

(I'm not responsible for any damage caused if you want to keep these lines after this point, till here it's safe)

#sid
deb http://cdn.debian.net/debian/ sid main non-free contrib
deb-src http://cdn.debian.net/debian/ sid main non-free contrib

 

so let's update your apt again

apt-get update

 

make your java 7 default

update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).
 
  Selection    Path                                            Priority   Status
* 0            /usr/lib/jvm/java-7-openjdk-kfreebsd-amd64/jre/bin/java   1071      modo automático
  1            /usr/bin/gij-4.7                                          1047      modo manual
  2            /usr/lib/jvm/java-7-openjdk-kfreebsd-amd64/jre/bin/java   1071      modo manual
 

just make sure to set jre or jdk 1.7 in my case i set "0" (ZERO)

 

checking your java version (if you get > 1.5 contrat's you can run and play Pokemmo on your debian based system)

java -version

[spoiler]

java version "1.7.0_25"

OpenJDK Runtime Environment (IcedTea 2.3.12) (7u25-2.3.12-4)

OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

[/spoiler]

I found a link that tells me how to put a Debian APT on my iphone, if I install java 7 on it, would it work? I'm not very good with these kinds of things but I'm really curious. Any help to get this game on my iphone is appreciated!

Java 7 is no longer being update and everyone should be installing Java 8 from now on.

I will be locking this because it is no longer relevant.
