The while loop has no body because of the semicolon.

Using the following code your program will work as per your requirements :

import java.util.*;
class Example
{
    public static void main(String args[])
    {
        Scanner input=new Scanner(System.in);
                         int[] x=new int[4];
                         String[] y=new String[5];
                         char r;
        System.out.print("How Many Student Detail Do you want Enter  :");
                         int count=Integer.parseInt(input.nextLine());
        for(int i=1;i<=count;i++)
        {
                             System.out.print("Enter student ID :");
                             x[i]=Integer.parseInt(input.nextLine());
                             System.out.print("Enter student Name :");
                                              y[i]=input.nextLine();
 
         }    
 
                         do 
        {
            System.out.print("Student has been added successfully.Do you want to add a new student (y/n) :");
                             r = input.next().charAt(0);
            count=1;  
            System.out.print("Enter student ID :");
                             x[count]=Integer.parseInt(input.nextLine());
                             System.out.print("Enter student Name :");
                                              y[count]=input.nextLine();
 
                         } while (r == 'y');
 
    }
}
