no java does not have a pointer but we can use the new operator

for ex:

the name of the method is firstname

we can create a objectas

firstname f=new firstname

this allocates the memory according to the size of the method firstname

Java do have pointers; but not similar to the one that C has. In Java, Pointers are in the form of Objects/references. Also the pointers in Java are not explicit like C. probably JVM internally uses pointers. Every object is a reference to a location making it a pointer...these pointers cannot be directly manipulated.

Differences between the C & Java pointers:

1) A pointer is a variable that holds the memory address of data. In Java 
there are only references, which do not hold any memory address, but 
which are indices in a table and this table has then the real pointer to 
the data.

2) Pointer Arithmetic is not possible with Java pointers.

These are my conclusions ...... What u all people think about this?

Yes, Java definately supports POINTERS . But we are not using them externelly. the Java Runtime Environment (JRE) will take care of it. Generally it always a tough task to use pointers by the users. In order to overcome this Java developers make the pointers that should be used internally.
In Java...,Every time when we create an object ..we have to create them by using " new " operator which is generally used for pointers.....
