Anyone can give me the variable description for this program:-
I will mark you as the brainiest
import java.Scanner;
class bubble sort{
public static void main(String[]args){
Scanner sc=new Scanner(System.in);
int arr[]=new int[15];
System.out.println("Enter 15 element in the array ");
for(int i=0;i<15;i++)
arr[i]=kb.nextInt();
int temp;
int x=arr.length();
for(int i=0;i
for(int j=0;j<=x-1;j++){
if(arr[j]>arr[j+1])
{
temp=arr[j];
arr[j]=arr[j+1];
arr[j+1]=temp;
}
}
}
System.out.println("Sorted array is as follows");
for(int i=0;i
System.out.println(arr[i]+"");
}
}
}

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]);
}
}
Output:
Enter the number of integers to sort:
6
Enter 6 integers:
12
6
78
9
45
08
Sorted list of integers:
6
8

Bubble sort program for sorting in descending Order
In order to sort in descending order we just need to change the logic array[j] > array[j+1] to array[j] < array[j+1] in the above program. Complete code as follows:
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]);
}
}
Output:
Enter the number of integers to sort:
6
Enter 6 integers:
89
12
45
9
56
102
Sorted list of integers:
102
