Java doesn't allow direct access to memory like C/C++.
Memory access violations are the root cause of 90% (approx,
maybe more) of all software bugs/problems. This is also the
root cause of many viruses, etc. But there are many more
reasons why Java is secure...

objects have access levels(private,public,protected)
class file is in bytecode format(ie. encrypted)
