Question

in this example it prints out Student’s names and credits what users enter from keyboard to the Vector.

but i wanna only print out Vectors which has credits more than 30.

thanks for any help.

public class Main {


    public static void main(String[] args) {
       Teacher t = new Teacher("Prof. Smith", "F020");
       Student s = new Student("Gipsz Jakab", 34);


       Vector<Person> pv = new Vector<Person>(); 
       pv.add(t);
       pv.add(s);

       Scanner sc = new Scanner(System.in);
       String name;
       int credits;


       for (int i=0;i<5;i++){

         System.out.print("Name: ");
         name = sc.nextLine();
         System.out.print("Credits: ");
         credits = sc.nextInt(); 
         sc.skip("\n"); 

         pv.add(new Student(name, credits));
       }
       System.out.println(pv); 
       System.out.println("The size of the Vector is: " + pv.size()); 
    }
}

Answer 1

Would this work?

if (credits > 30){
    pv.add(new Student(name, credits));
}

instead of:

pv.add(new Student(name, credits));
