Your eclipse java version is not compliant with your OS.

Check whether the bitness of your OS match with your eclipse Java version

Don't use "rm -r" to remove installed software on Linux. Why do you do that?

You need to learn how to use your package manager for CentOS

Well it's not really in the scope of this TA - you need to look into the docs for your distro. I've always greatly preferred Debian packaging over rpms, so have never learned the latter. And - i don't know CentOS
I could work with you on it, but it would have to be a Live event

Hi,
I know CentOS is developed from Red Hat and I need to resolve such problem to Eclipse Neon.

Your immediate problem is not really to do with Eclipse - it's to do with the following

a. listing the versions of Java available in your package manager
b. using that package manager to get the latest versions

You want to get into your car - your goal is to go to some place. Your problem is that you haven't learned to drive properly yet. There are two solutions
a. learn to drive quickly
b. pay a chauffeur to drive for you

yum is the package manager for CentOS, what's the output of:

#yum list | grep -i jdk

and:

#yum list | grep -i jre

You have selected JDK 1.8 - this is OK.

You may add a JAVA_HOME variable and add it to your PATH. Check what you already have in your ~/.bash_profile

You need:

JAVA_HOME=/usr/lib/jvm/jre-1.8.0-openjdk.x86_64
export JAVA_HOME

PATH=${PATH}:${JAVA_HOME}:${JAVA_HOME}/bin
export PATH

Verify that you don't have multiple java home variables and no multiple locations in PATH where java resides.
