Hi I'm presently attempting to install apache tomcat on localhost since i have am likely to operate a new development project in Java. Will this be considered a problem basically have previously apache webserver set up in my local system already? maybe there is any port conflict or anything like this? Would appreciate any help. thanks.

No. Because Tomcat uses default port 8080 for that webserver as the "normal" webserver uses port 80 for html exhibiting. You are able to change that within the catalina qualities from the tomcat server but on first install the defaults aren't leading to issues with a port 80 webserver.
