                ad.PrintMarkFromTheArray();
            }
            else if (select == 3)
            {
                ad.PrintNameFromTheArray();
            }
            else if (select == 4)
            {
                ad.PrintNameMarkFromTheArray();
            }
            else if (select == 5)
            {
                ad.SendMark();
            }

Add

System.out.println("Enter The 1 for addnig data");
System.out.println("Enter The 2 for Waching the MARK data");
System.out.println("Enter The 3 for Waching the NAME data");
System.out.println("Enter The 4 for Waching All the data of students");
System.out.println("Enter The 5 for Waching SUM of the mark of Students");
System.out.println("Enter The 6 for Exit");

then 

Scanner scan = new Scanner(System.in);
int select = 0;
do {
    System.out.println("Enter your option");
    select = scan.nextInt();
    if (select == 1) {
        ad.AddListIntoArray();
    } else if (select == 2) {
        ad.PrintMarkFromTheArray();
    } else if (select == 3) {
        ad.PrintNameFromTheArray();
    } else if (select == 4) {
        ad.PrintNameMarkFromTheArray();
    } else if (select == 5) {
        ad.SendMark();
    }else if (select == 6) {
        System.out.println("Exiting...");
    }
    else {
        System.out.println("invalid input");
    }
} while (select != 6);

put your code inside while(true) loop.

Dialog dlg = new Dialog();
while(true){
    dlg.showDialog();
    dlg.progressInput();
}
