♣♣♣ WRITE A PROGRAM TO SORT EXISTING ARRAY. ♣♣♣

import java.io.*;

class pro7

{

            public static void main(String args[]) throws IOException

            {

            int cnt,last,i,j,temp;

            int arr[]=new int[10];

            InputStreamReader a=new InputStreamReader(System.in);

            BufferedReader b=new BufferedReader(a);

            System.out.print("Enter the total number of array : ");

            last=Integer.parseInt(b.readLine());

                        for(cnt=0;cnt

                        {         

                        System.out.print("Enter element"+(cnt+1)+" : ");

                        arr[cnt]=Integer.parseInt(b.readLine());        

                        }

                        for(i=1;i<=last;i++)

                        {

                                    for(j=1;j<=last;j++)

                                    {

                                                if(arr[j-1]

                                                {

                                                temp=arr[j-1];

                                                arr[j-1]=arr[j];

                                                arr[j]=temp;

                                                }

                                    }

                        }

                        System.out.println("Array after sorting is :");

                        for(cnt=0;cnt

                        {

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

                        }         

            }

}

OUTPUT :-

            Enter the total number of array : 5

Enter Element1 :23

Enter Element2 :12

Enter Element3 :45

Enter Element4 :33

Enter Element5 :21

Array after sorting is :

            45        33        23        21        12
