Question

Create an Eclipse Java project that utilize "Bubble Sort" to sort an unsorted integer array of size 10. The main method should display unsorted array and sorted array after Bubble Sort. NEED A WORKING JAVA PROJECT. NEED IT ASAP

Answer 1

import java.util.Scanner;

public class BubbleSortInt {

  //Bubble sort function
  public static void bubbleSort(int[] array) {
    for (int i = 0; i < array.length - 1; i++)
      for (int j = 0;j<array.length-i-1;j++)
        if (array[j] > (array[j + 1])) {
          int temp = array[j];
          array[j] = array[j + 1];
          array[j + 1] = temp;
        }
  }

  public static int[] readInput(){
    Scanner scanner = new Scanner(System.in);

    //Reading size of array
    int n = 10;
    //Reading n number of values to array
    System.out.println("Enter "+n+" values");
    int arr[] = new int[n];
    for(int i = 0;i<n;i++){
      arr[i] = scanner.nextInt();
    }
    return arr;
  }

  public static void main(String args[]) {
    int sub[] = readInput();

    // Printing unsorted array
    System.out.println("\nUnsorted array:");
    for(int i = 0;i<sub.length;i++)
      System.out.print(sub[i]+" ");
    System.out.println("\n");

    //Calling bubble sort
    bubbleSort(sub);

    //Printing the sorted array after calling bubbleSort function
    System.out.println("Sorted array:");
    for(int i = 0;i<sub.length;i++)
      System.out.print(sub[i]+" ");
    System.out.println();
  }
}
