Making the Appropriate method call?

So I'm not sure how to make the appropriate method call. I created all the following code below according to some of the stuff that I know and according to what I was asked for of the assignment. I did another assignment on assigning method calls to a main method but it was with integers not with scanner class or most of the content in this assignment. I was able to figure out most of what I needed except this. If there is anything else wrong with my code please tell me. Any help would be appreciated. This is for a class assignment. Thank you for your help. I tried this:

import java.util.*;
import java.util.Scanner;
public class Dba    {
    public static void printTicket (String name, String id, double price)
    {
        Random num = new Random();
        Scanner input = new Scanner(System.in);
          int x = 1000;
      int age;
      String space="";
      String firstResponder;
      String veteran;        
        
        System.out.println("Please enter your first name and last name, separated by a space:");
        name=input.nextLine();

        System.out.println("Are you a first responder?");
        firstResponder=input.nextLine();
        
        System.out.println("Are you a veteran?");
        veteran=input.nextLine();
        
        int randomNumber=num.nextInt(x)+1;
        
        space += name.charAt(0);
    int index=0;
    
          for(int i=0;i<name.length();i++)
      {
          if(name.charAt(i)==' ')
          {
              index=i;
              break;
          }
      }
      
        for(int i=index+1;i<name.length();i++)
      {
          space+=name.charAt(i);
      }
      
      
    
    System.out.println("Please Enter your Age: ");
    age=input.nextInt();
        if (age<3) 
        {
            price=2;
        }
        else if(age>=3 && age<=5)
        {            
            price=9;
        }
        else if(age>=6 && age<=18)
        {
            price=11;
        }
        else
        {
            price=12;
        }
        
        if(firstResponder.equals("yes") && age>18)
        {
            price=price*0.5;
            System.out.println("Because you are a first responder with over 18 years of age you get a 50% discount");
        }
        
        if(veteran.equals("yes") && age>18)
        {
            price=price*0.5;
            System.out.println("Because you are a veteran with over 18 years of age you get a 50% discount");
        }
            
        System.out.println("Welcome to APCS Carnival, " + name +"!");
        System.out.println("Your User ID is " + id);
        System.out.println("The cost of your ticket is $" + price + ".");
        System.out.println("Have a great time at the APCS Carnival today!");
   }
    
        public static void main(String[] args)
        {
        printTicket();
            

    }
}
