By default, I had Java 7 installed on my system(X64, Fedora 20).

I needed Java 6 for a software, hence had to remove 7.

sudo yum remove *java*

And then, I installed Java 6.

This installs Java 6 successfully. but the java compiler, JavaC is missing. For that, I try -

su -c "yum install java-1.6.0-openjdk-devel"

Loaded plugins: langpacks, refresh-packagekit
No package java-1.6.0-openjdk-devel available.
Error: Nothing to do

Could someone please help me with installing javac for java 1.6.

You can't remove javac by yum remove *javac*. javac is a binary and not a package. You also can't install OpenJDK 6 from official Fedora repositories because it is no longer available.

If it is a program that you want to run on JDK6 you could set compiler compliance level to 1.6 and it should work.

The easiest possible option would be to install Oracle JDK 6. You can install it along with your existing installation of any other Java using alternatives.

You can very easily adopt this guide to install Oracle JDK 6 on your Fedora 20.

  • Edited, the question. Could I have Sun Java instead, it tastes better. – Random Dude Jan 17 '15 at 15:34
  • You can very easily use the guide I linked in the post to install JDK 6 on your Fedora box. – Sudhir Khanger Jan 19 '15 at 9:21
