Answer / bharathi
Java has no pointers but it has reference. A reference is an
abstract identifier for an object and it tags every object
with a name in the jvm so that programmer can refer to it.
And it is completely hidden from the programmer in any case.

Answer / pratiksha
pointers are dangerous and lead to memory leaks, memory
corruption, invalid memory access, e.g. from uninitialized
and improperly initialized variables, indexing out of
bounds, and many bugs due to pointer arithmetic.
References, and other features related to these, avoid all
these problems.

Answer / diapk kumar sinha
Java has no need to contain pointers because, Because Java
is developed for fully system independent language, so in
the presence of pointer it may not perform like fully system
independent language. And the main thought is that removing
pointer is for security purpose and make it fully system
independent language to work at any platform.

application execution time.because of magic of byte code.
