Hi
Q:
What was LOST and What was GAIEND in java with not including the pointers in C++?
will i found that java have pointers.. they're just not explicit..and don't allow Pointer Arithmetic ...
so...can u plz answer the Q..
and plz.. give me an example "in C++" that i cannot do it in java..and how to get around it "in java"..
thank you ...

Less complexity and more stable applications. Downside: you can't randomly write into your RAM. Upside: you can't write randomly into your RAM.
Never rebooted my PC that much than when I was still writing C.

You'll be waiting a while, dude...
Pointers do not exist in Java... they are abstracted away from us, and we do not have access to them as Java programmers, (with very few exceptions).
ok.. i will write a c++ code and could someone
give me how its done in java <<i dont know java ..
void LinkList :: InsertSorted( int x)
{
if ( head == 0 || head ->data >x )
InsertFirst(x);
else
{
Node *q = head;
Node *p= head->next;
while( p != 0 && p->data < x)
{
q=p;
p= p->next;
}
node *r = new Node(x);
q->next= r;
r->next = p;
}
}
class LinkedList {
void insertSorted(int x) {
if (head == null || head.data > x) {
insertFirst(x);
}
else {
Node q = head;
Node p = head.next;
while (p != null && p.data < x) {
q = p;
p = p.next;
}
Node r = new Node(x);
q.next = r;
r.next = p;
}
}
}
ok..ok
the last code have some problems..
this is the right one
int T[100];
for (int i=0; i<99; i++)
T[i]=i;
int *ta= &T[54]; // is this possible in Java ?
// if yes then write it down please;
// if no.. then is their a way to get it done ..?
int *pT= &ta[41];//the same as the last commente;
pT++;//can this be done in java ?
// if yes then write it down please;
// if no.. then is their a way to get it done ..?
ta= NULL;
i hope i find the answer...

in my first post their was a Q ..
that Q is a part of an assignment from my
doctor in Computer Science College...
and i want to put some examples for him...

No, pointer arithmetic cannot be done in Java. It's a higher-level language than that. That's not to say that the actual problem - as opposed to "how do I do pointer arithmetic?" which relates to a proposed solution to a problem, not a problem itself - can't be solved in Java
