How To Install Java on LINUX and set the path variable


I have downloaded java and installed it with chmod +x and then ./bin package.

Hereunder is an output from CLI (putty)

I understand that the system knows the java is in a wrong place but if I do java -version it finds it correctly. I don't know and I don't understand how do I need to tell the OS that the java is somewhere else, I just did that with export java home and java path but still dosen't work, it keep tells when I do whereis java "java: /usr/share/java"

how do I fix this? What do I need to do?

here is another output that might help:
