Windows XP's Task Manager is a very useful tool when it comes to troubleshooting problems. Not only does it help you terminate hung applications, but it also provides you with detailed information about all the processes currently running on your computer.

When you select the Processes tab, the default detail view displays four columns of information about each process:
* IMAGE NAME: The name of the process.
* USER NAME: The user who started the process.

Pointers can crash the system. So, they are not used in java.

The Java Language the referencing and dereferencing of objects is handled for you automatically. Java does not allow you to manipulate pointers or memory addresses of any kind. It does not allow you to cast object or array references into integers and It does not allow you to do pointer arithmetic. It does not allow you to compute the size in bytes of any primitive type or object. There are two reasons for these restrictions:

Pointers are a notorious source of bugs. Eliminating them simplifies the language and eliminates many potential bugs. Pointers and pointer arithmetic could be used to sidestep Java's run-time checks and security mechanisms. Removing pointers allows Java to provide the security guarantees that it does.

To a C programmer, the lack of pointers and pointer arithmetic may seem an odious restriction in Java. But once you get used to the Java object-oriented programming model, it no longer seems like a serious restriction at all. The lack of pointers does mean that you probably can't do things like write UNIX device drivers in Java (at least not without using native methods written in C). But big deal--most of us never have to do this kind of low-level programming anyway.

Well joydeep! The references in Java are a lot like pointers. As a matter of fact the Java Language Specification defines references to be pointers to objects. Some things that can be done with say C pointers but not with Java references is pointer arithmetic and dereferencing. This allows the Java references to be much safe and less error prone.
