Question

write a program in java to accept a set of 20 integers in a single dimensional array. sort the numbers in ascending order using the bubble sort technique. display the sorted array.

Answer 1

Answer:

import java.util.Scanner;

class BubbleSortExample {

 public static void main(String []args) {

   int num, i, j, temp;

   Scanner input = new Scanner(System.in);

 

   System.out.println("Enter the number of integers to sort:");

   num = input.nextInt();

 

   int array[] = new int[num];

 

   System.out.println("Enter " + num + " integers: ");

 

   for (i = 0; i < num; i++)  

     array[i] = input.nextInt();

 

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

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

       if (array[j] > array[j+1])  

       {

          temp = array[j];

          array[j] = array[j+1];

          array[j+1] = temp;

       }

     }

   }

 

   System.out.println("Sorted list of integers:");

 

   for (i = 0; i < num; i++)  

     System.out.println(array[i]);

 }

}
