2d array

...... i just want to store 2d array in arraylist and print it. can you just post me the link where i can read about it?

thanks

which do you think the best choose of what iam trying...

SomeClass smcls = aa.get(x);
AnotherClass anCls = smcls.get(y);

but with this i will have to make two more classes???

i am sure there is a way in java so i dont need to create classes. i just...

yes, i am not using array tho. i am using arraylist. variable aa is arraylist.
ex: there is no array here.

for(int y = 0; y < aa.size(); y++) {
for(int x = 0; x < aa.size(); x++){
...

like aa.add(bb); //thats why it was print so much data on output

and to print arraylist would you print like 2d array?
1st add so two loops or you wont need the two loops
2nd print

so to store 2d array in 2d arraylist you have to do this below:



ArrayList<int[][]> aa= new ArrayList();
int bb[][] = { {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},
...
