How lucrative is Java Certification in Nigeria

Hello guys, Please, I'll like to know how lucrative Java Certification is in Nigeria.

Is it a sought-after programme in the Nigeria IT world? or I'm just wasting my time?

I'm new to the IT world and a chemical/petroleum engineering graduate

Thanks in advance for your advice.

a friend of mine who did java said its not very lucrative in naija.he studied other IT fields which he is current working with.for me.i have ccna and have not found a good job too.so,which way then?
