System.out.println("Enter 1 to Add a Record");
System.out.println("Enter 2 to Print the Records");
System.out.println("Enter 3 to Delete a Record");
System.out.println("Enter 4 to Edit a Record");
int x=abir.nextInt();
switch(x){
  case 1:
    System.out.println("Enter Student Name");
    String x1=abir.nextLine();
    System.out.println("Enter Student Id");
    String x2=abir.nextLine();
    System.out.println("Enter Student Department name");
    String x3=abir.nextLine();
    System.out.println("Enter Student Contact info");
    String x4=abir.nextLine();
    bo.AddInlist(x1,x2,x3,x4);
    break;
  case 2:
    bo.PrintRecord();
    break;
  case 3:
    System.out.println("enter your desire deleting id");
    String x5=abir.nextLine();
    bo.DeleteRecord(x5);
    break;
  case 4:
    System.out.println("enter your desire Edited id");
    String x6=abir.nextLine();
    bo.EditRecord(x6);
    break;
  default:
    System.out.println("Wrong Entry.. Follow the Instructions");
    System.out.println();
}
System.out.println("Enter 1 to Add a Record");
