I need your help

For this one I need to create delivery class for a delivery service .however, this class should contain (delivery number which contains eight digits. The first four digits represent the year; the last four represent the area. E.g, the 76th delivery in 2010 has a complete delivery number of 20100076). (Code to representing the delivery area either 1 for local delivery or 2 for long distance delivery). (Weight in kg of the item to be delivered).at the end the fee for the delivery as follows:
Distance Weight Fee (RM)
1 Under 5 kg 12.00
1 5 ? 20 kg 16.50
1 Over 20 kg 22.00
2 Under 5 kg 33.00
2 5 kg or more 45.50

Create a constructor for the Delivery class that accepts arguments for the year, delivery number within the year, delivery distance code and weight of the package. The constructor determines the eight-digit delivery number. Also include these methods to (set the delivery fee, set and get every Delivery object field, display every Delivery object field)
The file name is Delivery.java
Next, create an application that prompts the user for data for a delivery. Keep prompting the user for each of the following values until they are valid:
? a four digit year between 2010 and 2025 inclusive
? a delivery number for the year between 1 and 9999 inclusive
? a package weight between 0.10 kg and 100 kg inclusive
? a delivery code distance that is either 1 or 2.
When all data entries are valid, construct a Delivery object and then displays its values. The system will be terminated if the entry value for delivery code is -1. Save the file name is ApplicationDelivery.java
Your program must follow proper Java standards, implement selection and repetition structure, and include comments to describe the purpose of the program.

Hi Friend,

Try the following code:

import javax.swing.*;
import java.util.*;
class Delivery {
int year;
int deliveryNo;
double weight;
int code;

Delivery(int year,int deliveryNo,double weight,int code){
year=year;
deliveryNo=deliveryNo;
weight=weight;
code=code;
}
public double displayFees(int c,double w){
double fees=0;
if(c==1){
if(w<5){
fees=12.00;
}
else if((w<20)&&(w>5)){
fees=16.50;
}
else if(w>20){
fees=22.00;
}
}
else if(c==2){
if(w<5){
fees=33.00;
}
else if(w>=5){
fees=45.50;
}
}
return fees;
}
}
public class ApplicationDelivery{
public static void main(String []args){
Scanner input=new Scanner(System.in);
System.out.print("Enter year: ");
int y=input.nextInt();
while((y<2010)||(y>2025)){
System.out.println("Year should be in the range of (2010 - 2025).");
System.out.print("Please re-enter year: ");
y=input.nextInt();
}
System.out.print("Enter delivery no: ");
int no=input.nextInt();
while((no<1)||(no>9999)){
System.out.println("Delivery No should be in the range of (1 - 9999).");
System.out.print("Please re-enter delivery no: ");
no=input.nextInt();
}
System.out.print("Enter weight: ");
double w=input.nextDouble();
while((w<.10)||(w>1000)){
System.out.println("Weight should be in the range of (.10kg - 100kg).");
System.out.print("Please re-enter weight: ");
w=input.nextDouble();
}
System.out.print("Enter delivery code: ");
int code=input.nextInt();
while((code<1)||(code>2)){
System.out.println("Code No should be either 1 or 2.");
System.out.print("Please re-enter code: ");
code=input.nextInt();
}
String num=Integer.toString(no);
String year=Integer.toString(y);
if(num.length()==1){
num="000"+num;
}
else if(num.length()==2){
num="00"+num;
}
else if(num.length()==3){
num="0"+num;
}
String delNo=year+num;
Delivery del=new Delivery(y,no,w,code);
double fees=del.displayFees(code,w);
System.out.println(code+" "+delNo+" "+w+" "+fees);
}
}

Thanks
