I am doing a payment code. But its not working. How can I make it work?

Edit: Now I have change my code a bit. It can run now but it still didn't print the output I wanted. It only prints 2 lines out of all the output I wanted. I have no idea what was the problem but I think it was at the main part. Any suggestions?

 import java.util.Scanner;
 public class BusPayment 
 public int number_of_adults;
 public int number_of_children;
 public double adult_price;
 public double children_price;
 public double totalprice;

 public BusPayment()

 

 public int getnumber_of_adults()
 return number_of_adults;
 

 public int getnumber_of_children()
 return number_of_children;
 

 public double getadult_price()
 return adult_price;
 

 public double getchildren_price()
 return children_price;
 

 public double gettotal_price()
 return totalprice;
 

 public void setadult_price(double adult_p)
 adult_price=adult_p; 
 

 public void setchildren_price(double children_p)
 children_price=children_p;
 

 public void settotalprice(double total_price)
 totalprice=total_price;
 

 public BusPayment(double adult_p, double children_p)
 adult_price=adult_p;
 children_price=children_p;
 

 public void BusPaymentPart()
 number_of_adults=0;
 number_of_children=0;
 adult_price=15.00;
 children_price=10.00;
 totalprice=0.00;
 

 public double calculate_totalprice()
 number_of_adults= 0;
 number_of_children= 0;
 totalprice= (number_of_adults*adult_price)+ 
 (number_of_children*children_price);
 return totalprice;
 

 public static void main (String []args)
 BusPayment test = new BusPayment();

 Scanner input=new Scanner(System.in);
System.out.println("Payment");
System.out.println("The price of an adult ticket is RM15.00.");
 System.out.println("The price of a children's ticket is RM10.00.");

 int number_of_adults=input.nextInt();
 System.out.println("The number of adults are: " +number_of_adults);
 number_of_adults=input.nextInt();

 int number_of_children=input.nextInt();
 System.out.println("The number of children are: "+number_of_children);
 number_of_children=input.nextInt();

 double totalpri = test.calculate_totalprice();
 System.out.println("The total price you need to pay: " +totalpri);

I wanted the output to be like:

The price of an adult ticket is 15.00. (this was printed)

The price of a children's ticket is 10.00. (this was printed)

The number of adults are:

The number of children are:

The total price you need to pay:

Payment Successful!

It looks like you are calculating the values after you are trying to print them:

System.out.println("The number of adults are: " + number_of_adults);
System.out.println("The number of children are: " + number_of_adults);
System.out.println("The total price you need to pay: " + totalprice);
calculate_totalprice();

Also, you are calling a non-static method calculate_totalprice() from within static scope:

public static void main (String []args)
 ...
 calculate_totalprice(); 

I think you might need to call the calculations first.

calculate_totalprice();

System.out.println("The number of adults are: " + number_of_adults);
System.out.println("The number of children are: " + number_of_adults);
System.out.println("The total price you need to pay: " + totalprice);
