Bubble Sort In Java

Code :


public class BubbleSort {
    static int swapCount=0;
    static int passes=0;
   
   
    public static void main(String[] args) {

        int[] array={5,1,4,2,8};
       
        printArray(array);//Before
       
        bubbleSort(array);
       
        printArray(array);//After
       
        System.out.println("\n Total Passes:"+passes);
       
        System.out.println("\n Total Swaps:"+swapCount);
    }

    private static void bubbleSort(int[] array) {
        boolean swapped=false;                        //Needed to check if the pass swapped elements
        do{                                           // needed as the loop should be entered atleast once
            swapped=false;                            //keeping it false before entering the Pass
            for(int i=0;i<array.length-1;i++){
            if(array[i+1]<array[i]){                // If numbers are not in place swap
                swap(i+1,i,array);                  // swap funtion
                swapped=true;                       // elements swapped hence make it true
            }
            passes++;                               // just for reporting
        }
        }while(swapped);
        System.out.println();
    }
   
    private static void swap(int a,int b,int[] arr){ // utility function to swap elements
        int temp=arr[a];
        arr[a]=arr[b];
        arr[b]=temp;
       
       
        System.out.println("\n Swapping a:"+arr[a]+"  b:"+arr[b]);
        swapCount++;                                  // reporting the total swaps
    }
