Program Listing

public class  Main {

    public static void bubble_sort(int[] arr) {

        int n = arr.length;

        for (int i = 0; i < n - 1; i++) {

            for (int j = 0; j < n - i - 1; j++) {

                if (arr[j] > arr[j + 1]) {

                    int temp = arr[j];

                    arr[j] = arr[j + 1];

                    arr[j + 1] = temp;

                }

            }

        }

    }

    public static void main(String[] args) {

        int[] arr = {-5, 134, 6, 450, 235, 15,51};

        

        System.out.println();

        System.out.println("\tBubble Sort in Java\n");

        

        System.out.println("UnSorted Values");

        for (int i = 0; i < arr.length; i++) {

            System.out.print(arr[i] + " ");

        }

        System.out.println();

        

        bubble_sort(arr);

        

        System.out.println("Sorted Values");

        for (int i = 0; i < arr.length; i++) {

            System.out.print(arr[i] + " ");

        }
