# alternatives --install /usr/bin/jar jar /opt/jdk1.7.0_79/bin/jar 2
# alternatives --install /usr/bin/javac javac /opt/jdk1.7.0_79/bin/javac 2
# alternatives --set jar /opt/jdk1.7.0_79/bin/jar
# alternatives --set javac /opt/jdk1.7.0_79/bin/javac

java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

# export JAVA_HOME=/opt/jdk1.7.0_79
# export PATH=$PATH:/opt/jdk1.7.0_79/bin
