Java Bubble Sort Example
This Java bubble sort example shows how to sort an array of int using bubble
sort algorithm. Bubble sort is the simplest sorting algorithm.

//create an int array we want to sort using bubble sort algorithm

for(int i=0; i array [1] swap it.
* 3. Compare array[1] & array[2]
* 4. If array[1] > array[2] swap it.
* ...
* 5. Compare array[n-1] & array[n]
* 6. if [n-1] > array[n] then swap it.
*
* After this step we will have largest element at the last index.
*
* Repeat the same steps for array[1] to array[n-1]
