Question

Write a program with java editor is about the student system, you need to write some simple and uncomplicated student information, then use 2D-Aarraylist to edit some simple code, and then when the user chooses the command, it must be casually selected, according to the user. The request to execute the command, for example when the user selects (student, id, gpa, etc.) wants to remove it.
Have any questions to ask me, because my homework is not required to add some code according to my idea, thank you

Answer 1

here is the answer........

package student;
import java.util.*;

public class Student {


public static void main(String[] args) {
   int i, q, z, c, b;
   int x=0;
   String[] name = new String[30];
   int[] age = new int[30];
   String[] course = new String[30];
   String[] year = new String[30];
   String[] section = new String[30];
   int menuChoice;

   Scanner input = new Scanner (System.in);

   start:
   do{

       System.out.println("\t\t\tStudent Record Menu");
       System.out.println("\t\t1. Add Student\t2. View Students\t3. Search Student\t4. Exit");
       System.out.println("Enter a choice: ");
       menuChoice = input.nextInt();

       if (menuChoice==1)
       {
           for (z=x; z<=29; z++)
           {
               System.out.println("Full name:");
               name [z] = input.nextLine();
               System.out.println("Age:");
               age [z] = input.nextInt();
               System.out.println("Course:");
               course [z] = input.next();
               System.out.println("Year:");
               year [z] = input.next();
               System.out.println("Section:");
               section [z] = input.next();
               x++;
               continue start;
           }
       }
               else if (menuChoice==2)
               {
                   for (i=0; i<x; i++)
                   {
                       System.out.println(name[i] + age [i] + course [i] + year [i] + section [i]);
                   }
               }

   } while (menuChoice<4);

}
}
