Swapping the numbers in the position, the array becomes:

Index 0 1 2 3 4
Ar 21 16 12 10 2

The whole array has been sorted in descending order.

Program 10 Write a Java program to input “n” names and marks of “n” students in an array and sort the
numbers in an ascending order. (Use Bubble sort technique)

1 import java.util.*;
2 class Bubble_sort

3 {
4 public static void main(int nos)

5 {
6 Scanner sc= new Scanner(System.in);

7 String n[ ]=new String[nos];
8 int m[ ]=new int[nos];

9 int i, j, temp_marks;
10 String temp_name;

11 for (i=0; i<nos; i++)
12 {

13 System.out.print("Enter a name: ");
14 n[i] =sc.next();

15 System.out.print("Enter marks: ");
16 m[i] =sc.nextInt();

17 }
18 for(i=0; i<nos-1; i++)

19 {
20 for(j=0; j<nos-1-i; j++)

21 {
22 if(m[j]>m[j+1])
23 {

24 temp_marks = m[j];

25 m[j]=m[j+1];
26 m[j+1]=temp_marks;
27

28 temp_name = n[j];
