JRE
JRE on 32-bit and 64-bit Debian / Ubuntu / Mint Linux operating systems.
End users looking for java to run software are looking for JRE. OpenJRE / OpenJDK is an alternative to Oracle Java that is the default on packaged linux systems such as Ubuntu / Kbuntu / Mint.
Are you 32 or 64 bit? Type:
uname -m
Have you downloaded Oracle Java? as of TOR you could find it [ here ] and the file you need is/was called [ jre-8u181-linux-x64.tar.gz ]
note: jre-8u181-linux-x64.tar.gz for 64 bit, jre-8u181-linux-i586.tar.gz 32 bit, and adjust the version number or build number for what is current at the time you are reading this. (as of 2018 there is a jre 10, however, many software recommends jre 8). Companies like Oracle tend to move things around on their website unnecessarily often, so more than a week after TOR that link is probably defunct.
Adjust any version numbers to accommodate your system, otherwise instructions assume currents as of TOR: typically OpenJDK version 7. To REMOVE OpenJDK and install Oracle Java JRE do the following.
1. remove OpenJDK
sudo apt-get autoremove openjdk-7-jre
2. confirm complete removal (other instructions online do not accomplish this ie WikiHow)
sudo java -version
You should see the error: No such file or directory <- that is good!
3. make a home
sudo mkdir /usr/local/java
4.
