Array looping

Question

Hi,
I need to run several nested loops. Problem is, I only know how many nested ones to do at runtime (not compile). eg. want to do something like this
imagine I have an int[] array.
int[] r;
Someone else initialises and populates this. Now I now that r is 7 dimensional, but do not know at compiletime.
for (int a = 0;a<5;a++) {
for (int b = 0;b<6;b++) {
for (int c = 0;c<6;c++) {
for (int g=0;g<4;g++) {
r[0]=a;
r[1]=b;
r[6]=g;
etc.
How can i do this without hard coding in the looping structures such that this can handle an array of an arbitrary dimension (just single array though - not [][]).
Thanks for help.

Answer 1

My code above will have 5 nested iteration with 4 x 2 x 3 x 5 x 4
But one thing I don't get it.. when you compile, it won't compile because I note some part of code are messed up with the Jive syntax highlighting.
For example:
counter<i>++;
should be
counter[ i ]++;Gosh!
So here I re-post the code again:
public class x {
void doLoop(int[] looper) {
    int counter[] = new int[looper.length];
    int r[] = new int[looper.length];
    boolean keepLooping = true;
    while(keepLooping) {
       int i=0;
       while (true) {
           counter[ i ]++;
           if (counter [ i ] <= looper [ i ])
              break;
           else {
              counter=0;
if (i+1==looper.length) {
keepLooping = false;
break;
i++;
if (keepLooping) for (i=0; i<looper.length; i++) {
r[i] = counter[i];
System.out.print("r[" + i + "]=" + r[ i ] + " ");
// now do something with r[]
System.out.println("");
public void doSomething() {
int[] looper = new int[] { 4, 5, 3 ,2 ,4 };
doLoop(looper);
public static void main(String[] s) {
new x().doSomething();
Hope it would be all right this time...
