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...
Java provided with FireWall between a networked application
and your computer.
objects have access levels(private,public,protected)
class file is in bytecode format(ie. encrypted)
