nurexg,

your post sounds very cryptic, but if I understand what you are saying, you are looking at a 3D-array if you ask me.

As for multiplying n times, again this sounds very cryptic, so I will pass on that one.

Assuming my first line above is correct, then you can do something like this:

for(i=0; i<arraySize; i++) {
do stuff
for(j=0; j<arraySize; j++) {
do stuff
for(k=0; k<arraySize; k++) {
do stuff
}
}
}

Of course, this is generic. It all depends on what you are trying to do. Perhaps a quick google for "java 3d arrays" is in order?

I hope this helps.

coming to think of it again, i think u need a 2D-array

for(i=0; i<3; i++) {
print i
for(j=0; j<3; j++) {
print j
}
}

Again, very generic, but you should see where this is going. Hopefully this helps.

guys i try all but still not working any more idea.
