Maybe this is the wrong place for your question, because it has nothing to do with Java, but if you install a software, then all files will be copied to the right place and additionally some registry and path settings are done by the setup. If you copy a software, then you can be lucky if it works, but in 90% it will not work correctly, because you will not find all files and the registry and path settings are missing.
Hi Psantosh Installing usually means having some install program like InstallShield that copies the files into the right directory and sets up some registry entries. Simple Java programs can normally be "copied", because simple Java programs usually don't need registry entries. Search shareware sites for installers. By the way, a "please" somewhere in your sentence wouldn't hurt your case..
