Basic Java Question

[buzzdsm]

I'm 2 weeks in a basic Java class and I'm having all kinds of problems with an assignment. Here is the assignment(in red). Can someone help a newbie out?

Use this UML diagram to create the class

InternetCharges

-pkg:char
-hours:double
+InternetCharges(p:char, h:double)
+setPkg(p:char):void
+setHours(h:double):void
+getPkg():char
+getHours():double
+getChanges():double


XY_Prog4_11 Modify the data in the program so it matches these Sample Runs:

Welcome to Satellite Internet Connect
Packages:
A: 512Kbps $49.95, 40 hrs/month, $2/hr over 40 hrs
B: 1.0 Mbps $69.95 80 hrs/month, $1/hr over 80 hrs
C: 1.5Mbps unlimited hours
Enter the customer's package A, B, or C: A
Enter the number of hours used: 45
The charges are $59.95


Welcome to Satellite Internet Connect
Packages:
A: 512Kbps $49.95, 40 hrs/month, $2/hr over 40 hrs
B: 1.0 Mbps $69.95 80 hrs/month, $1/hr over 80 hrs
C: 1.5Mbps unlimited hours
Enter the customer's package A, B, or C:



Here is what I have so far

import java.util.Scanner;   //Scanner class

/**
 *This program demo's internet charges
 */
 
 public class IntChargesRun
 {
 	public static void main(String[] args)
	{
	   String input;
		char pkg;        //Package A, B, or C
		double hours;    //Number of hours used
	
		
		Scanner keyboard = new Scanner(System.in); //Scanner for keyboard input
		
		
		
		//Display instructions
		System.out.println("Welcome to Satellite Internet Connect Packages:" + '\n' +
								 "A: 512Kbps $49.95, 40 hrs/month, $2/hr over 40 hrs" + '\n' +
								 "B: 1.0Mbps $69.95, 80 hrs/month, $1/hr over 80 hrs" + '\n' +
								 "C: 1.5Mbps unlimited hours" + '\n');
								 
		//Customers package type
		System.out.println("Enter the customer's package A, B, or C: ");
		pkg = input.charAt(0);                    //Gets the first character
		
		//Number of hours used
		System.out.println("Enter the number of hours used: ");	
		hours = keyboard.nextDouble();            //gets hours
		
		InternetCharges ichgs = new InternetCharges(pkg, hours);
		double c = ichgs.getCharges();
		System.out.println (c);	
		
			
		}
	}

public class InternetCharges
{
	private char pkg;   			//Customers package
	private double hours;		//Number of hours used
	
	/**
	 *The constructor uses two parameters to accept
	 *arguments: p and h. The value in p is assigned to
	 *the pkg field and the value in h is assigned to
	 *the hours field. The InternetCharges method is called
	 */
	 
	 public InternetCharges(char p, double h)
	 {
	 	pkg=p;
		hours=h;
	 }

   /**
	 *The getPkg method returns the pkg field
	 */
	 
	 public char getPkg()
	 {
	 	return pkg;
	 }
	 
	/**
	 *The getHours method returns the hours field
	 */
	 
	 public double getHours()
	 {
	 	return hours;
	 }
	 
	/**
	 *The getCharges method returns the charges field.
	 */
	 
	 public double getCharges()
	 {
	 		
	 	if (pkg = A)
		baseCharge = 49.95;
		addedCharge = (hours - 40)* 2.00;  //2.00 per hour
		totalCharge = baseCharge + addedCharge;
		else if (pkg = B)
		baseCharge = 69.95;
		addedCharge = (hours - 80) * 1.00;  //1.00 per hour
		totalCharge = baseCharge + addedCharge;
		else if (pkg = C)
		baseCharge = 79.95;
		totalCharge = baseCharge;
	
		return charges;

	 }
	 }

This is a basics class so check the basics:

Did you declare your variables properly before using them?
What's the difference between 'A' and just A in the source code?
What is a programming block? How to start and end a block? How are If..Else blocks constructed?
