basic conditions and loops

1. Bus Ticket Counter

Story:
A conductor issues tokens to passengers. Each passenger must get a number in sequence.
Why: Helps students learn loops.
Logic:

  • Input: number of passengers.
  • Use for loop to print numbers 1 to n.
  • Extension: use if inside loop to print only even tokens.
Program:

import java.util.Scanner;
public class tokens{
    public static void main(String[] args){
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter number of passengers:");
        int n=sc.nextInt();
        for(int i=1;i<=n;i+=2){
            System.out.println("Only print even numbers:");
        }
    }
}

OUTPUT:
