Add the above lines in the /etc/profile just below comments.
$vi /etc/profile
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.
after the end of comments like above set the path. write the JAVA_HOME,PATH here.
/etc/profile needs root or admin access.if you are the admin then use sudo.

for example
sudo  vi /etc/profile.

$vi /etc/profile.

logout and login again, reboot,

or enter the below command
$source /etc/profile

to apply changes immediately in your current shell.
