A Brilliant Program: Insert an element into an array

INSERT AN ELEMENT INTO AN ARRAY:
import java.io.*;
class insert
{
 public static void main()throws IOException
 {
 BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
 System.out.println("Enter the number of elements in the array");
 int n=Integer.parseInt(br.readLine());
 int len=n+1;
 int Arr[]=new int[len];
 System.out.println("Enter the values");
 for(int i=0;i<n;i++)
 Arr[i]=Integer.parseInt(br.readLine());
 System.out.println("Enter the element to be inserted");
 int num=Integer.parseInt(br.readLine());
 System.out.println("Enter the index of the position of insertion of new element");
 int index=Integer.parseInt(br.readLine());
 for(int i=n-1;i>=index;i--)
 {
 Arr[i+1]=Arr[i];
 }
 Arr[index]=num;
 n++;
 System.out.println("THE ARRAY AFTER INSERTION");
 for(int i=0;i<n;i++)
 System.out.print(Arr[i]+"\t");
 }
}
