Thread: Issue with running DataGimmick program

good day all,
i am having an issue with running my program, i am not sure where i have gone wrong, i would appreciate it if someone could help me asap.

Thank you

here is what i was instructed to do:
You are to write a program for the DataGimmick wireless data provider company. The company
has three possible plans that consumers can sign up for, as follows:
Package: Monthly Fee: Included MB: Cost Per Additional (up to) 150 MB:
A $9.99 150 14.99
B $24.99 500 12.99
C $39.99 2000 8.99
Note that additional data beyond the “Included MB” may only be bought in increments of 150MB,
even if only a portion as little as 1 additional MB is used.
Your task is to write a program that:
• prompts the user for and reads in the exact number of MB of data they used (which cannot
have a fractional portion).
• prompts the user to enter the letter corresponding to their plan and reads in that plan’s letter.
• prints out the total monthly charge (in dollars and cents) for data usage for that user, based
on what they entered.

here is my code:

import java.util.*;
 
public class DataGimmick
{
 
 
 
   public static void main(String [] args)
   {
	  public static void main(String [] args)
   {
	   double cost;
		   int data;
		   double fee;
		   double additional;
		   Scanner myReader = new Scanner(System.in);
		   char A;
		   char B;
		   char C;
		   String option;
		   // Prompt User for the data usage.
		   System.out.print("How Much Data Did You Use?");
		   data = myReader.nextInt();
 
			// Prompt User for the package plan.
		   System.out.print("Which Plan Are You Using?");
		   myReader.next();
 
 
 
 
	   //Calculate the cost for different packages.
 
	   if (option A);
	   {   
 
		   fee = (data - 150) / 150;
		   cost = fee * 9.99;
	   }   
 
 
	   if ((data - 150) % 150 != 0);   
	   {   additional = cost + 14.99;
 
	   }
 
 
	   if (option = B);
	   {
 
	       fee = (data - 500) / 500;
	       cost = fee * 24.99;
	   }
 
	   {
	   if ((data - 500) % 500 != 0);   
	   {   additional = cost + 12.99;
 
	   }   
 
 
 
	   if (option = C);
	   {
 
	       fee = (data - 2000) / 2000;
	       cost = fee * 39.99;
	   }
 
 
 
	   if ((data - 2000) % 2000 != 0);   
	   {   additional = cost + 8.99;
 
	   }
 
 
	 //Print out the total monthly charge for data.
	   System.out.printf("Your bill for the month is $%,.2f\n", cost + additional); 
	   }
    }
