[Q]Using both jdk1.2.2 and jdk1.1.8

I installed jdk1.2.2 on my Windows98 system and I have no problem at all with using jdk1.2.2.
And now I'm thinking of installing another version of jdk, jdk1.1.8.

If I installed jdk1.1.8 on my system, would there happen any problem?

Any answer will be appreciated.
