Sort array elements in ascending order/Bubble sorting algorithm in ascending order

CODE:

import java.util.*;

class Ascend

{

     public static void main(String args[])

     {

           int i,j,n,temp;

           Scanner sc = new Scanner(System.in);

           System.out.println("Enter number of elements:");

           n=sc.nextInt();

           int a[]=new int[n];

           for(i=0;i<=n-1;i++)

           {

                System.out.print("enter a no:");

                a[i]=sc.nextInt();

           }

           for(i=0;i<=n-2;i++)

           {

                for(j=0;j<=n-2;j++)

                {

                     if(a[j]>a[j+1])

                     {

                           temp=a[j];

                           a[j]=a[j+1];

                           a[j+1]=temp;

                     }

                }

           }

           System.out.println("After sorting:");

           for(i=0;i<=n-1;i++)

           {

                System.out.println(a[i]);

           }

     }

}
