I thought I knew how to do that; I have been using Java for programming for ages. I had Ubuntu 13.10 on an Acer Chromebook C720 until earlier this week, when I made the mistake of installing Ubuntu 14.04, Not only does it load more slowly, but also it gvies errors with Java. I can do this
Quote:
sudo apt-get install openjdk-7-jdk
java -version
...and get the appropriate response 1.7.0_51 IcedTea etc,
but I want to use Java8, so I did what I have always done, something like this
Quote:
cd /usr
sudo mkdir java
sudo chown campbell java
cd java
tar -zxvf ~/Downloads/jdk-8-etc-linux-etc.tar.gz
and got the usual output, a list of files being created. Now if I try to use it, things go wrong.

Usage java RussianMultiplication <123> <456>
Default values 57 43 used
Multiply with * and /
57 * 43 = 2451
Multiply with << and >>
57 * 43 = 2451

It works all right with OpenJDK but the Oracle version doesn't. Whether it was exactly the same download as last week or a new download, I get that error. Similarly for Oracle Java7
Anybody else ever seen that error? I shall probably revert to Ubuntu 13.10 for the time being.
