Yes, you can make all static classes and put a driving script in a main method in Java. But, not matter what, you must put all of that in a class. Hence the charge: Java is Object Oriented Only. We say this, because every single line of operative code must be in a method and every single method must be explicityly placed into a class. You can't just write a driver: 
print "driver starting\n";
`call_system_util1`;
`call_system_util2`;
print "driver finished\n";

The equivalent code in Java must be in a method of some class. That's overkill in this case and it buys nothing except tedious typing, which is why we make the charge and it sticks.

There are two subtle bits of syntatic sugar here. First, Perl puts things in the main package by default. Second, code does not have to appear in a method/sub/function/whatever. It can just go in a driving script. Perhaps these differences seem small, but they are real.
