java is secure

[sanjay123456]

dear friends ,

we say that java is secure because its have no pointer so that virus do not affect our memory segment but we r using java and virus r coming means that where r coming those virus and how they affect ? while we have no pointer in java ?

Actually your assumption is incorrect. Everytime you create an object java is using pointers to that object. Java uses pointers everywhere, however it doesnt let the user make their own pointers. Thats the difference.

What makes you so sure it's the Java programs that are bringing the viruses?

I don't get the point to all this. What do you mean by Java "programe brings virus"? Java programs do not bring viruses. Viruses do not attack programming languages, they attack operating systems and files on the operating systems.

They might also attack bugs in the Java Virtual Machine in order to gain access to the underlying operating system. But in order for someone to do this they user would need to execute some .class file on their locally installed virtual machine. Unless you are talking about javascript but one has nothing to do with the other.
