I haven't tried that on CentOS 7, but it certainly works on CentOS 6. 
Java 1.7 is probably there already, and 1.6 can be installed via

yum install java-1.6.0-openjdk

The trick here is that java 1.7 and java 1.6 are provided by what's 
technically two different packages, as opposed to different versions of 
one package.

alternatives --config java

Let's you select which of the installed java releases will be started by 
the "java" program.

Note that this is not necessarily the same as what's run by the java 
plugin. For that, you may want to di

alternatives --config jre_openjdk


instead.
