Setting the default java compiler

Question

I have openjdk 1.8 installed via yum in '/usr/bin/java' and I have also downloaded the Oracle Java Hotspot 1.7 compiler in /opt/devel/jdk_1.7' I updated my PATH in my ~/.bashrc file to include/opt/dvel/jdk_1.7/bin'

When I run which java the terminal only responds with '/usr/bin/java'

Why is the other java compiler in '/opt/devel/jdk_1.7/bin' not being found?
How can I make this other compiler be the default compiler when executing java?

What does echo $PATH return? The very first path containing java dictates which version is executed. Note that the requirement to set JAVA_HOME in order to execute java is a fallacy. — Steve C

I would set JAVA_HOME too in ~/.bashrc

Setting JAVA_HOME

jdk7oracle=/opt/devel/jdk_1.7 
export JAVA_HOME=$jdk7oracle export
PATH=$JAVA_HOME/bin:$PATH

and then test using

java -version

Also make sure you start a new terminal session so that bashrc is reloaded after your edits. OR you can source the bashrc file if you don't want to restart terminal.

source ~/.bashrc
