# need help with two dimensional array that takes input from user and bubble sorts and selections sorts

I can get both of the sorts figured out but i cannot figure out how i can declare a two dimensional array without knowing how many elements are going to be in it. The number of elements will depend on how many words he/she types without using an array list. October 19, 2012 at 5:24 PM

Thank you. I am having problems with declaring the array. How do i do that without knowing how many elements are going to be input by the user? October 19, 2012 at 12:32 PM

Here is a code that performs Bubble Sort using 2 d array.

```public class BubbleSortWith2D {

public static void main(String[] args) {
int[][] a = {{3,24}, {4,56}, {1, 98}, {2,36}};

bubbleSort(a);

for(int i = 0;i<a.length;i++) {
String s = "";
for(int j=0;j<a[i].length;j++) s += a[i][j] + " ";
System.out.println(s);
}
}

public static void bubbleSort(int[][] array) {
while(true) {
boolean swapped = false;
for(int i=0;i<array.length-1;i++) {
if (array[i] > array[i+1]) {
swapped = true;
for(int j=0;j<array[i].length;j++) {
int t = array[i][j];
array[i][j] = array[i+1][j];
array[i+1][j] = t;
}
}
}
if (!swapped) return;
}
}
}
```
