I do not know how to initialize the two variables

[Daniel]

Hi, Your class will have an additional method that computes and returns the actual cost per month. This is defined as the total cost divided by the number of months.
I do not know how to initialize the two variables. help me please
this is my code:

Code:

public class LeaseEval
 {
 	private String custName; // customer's name
 	private double monthPay; // monthly payment
 	private int termLease; // the term of the lease in months
 	private double downPay; // down payment
 	private int maxFreeMiles; // maximun amount of free miles
 	private int overMaxMiles; // The charge per mile for all miles over the max
 	private double milesDriven; // The number of miles actually driven
 	
 	// I create a constructor
 	
 	public LeaseEva(String theCustName, double theMonthPay, int theTermLease,
 	double theDownPay, int theMaxFreeMiles, int theOverMaxMiles, double theMilesDriven)
 	{
 		custName = theCustName; 
 		monthPay = theMonthPay;
 		termLease = theTermLease;
 		downPay = theDownPay;
 		maxFreeMiles = theMaxFreeMiles;
 		overMaxMiles = theOverMaxMiles;
 		milesDriven = theMilesDriven; 
 				
 	}	
 	
 	// Here are the "gets" for the variables
 	
 	public String getTheCustName()
 	{
 		return custName;
 	}
 	
 	public double getTheMonthPay()
 	{
 		return monthPay;
 	}
 	
 	public int getTheTermLease()
 	{
 		return termLease;
 	}
 	
 	public double getTheDownPay()
 	{
 		return downPay;
 	}
 	
 	public int getTheMaxFreeMiles()
 	{
 		return maxFreeMiles;
 	}
 	
 	public int getTheOverMaxMiles()
 	{
 		return overMaxMiles;
 	}
 	
 	public double getTheMilesDriven()
 	{
 		return milesDriven;
 	}
 	
 	// the mathematical part of the program is here
 	
 	public double costperMonth()
 	{
 		double totalCost;
 		double numMonths;
 		double costMonth;
 		
                                // THESE TWO VARIABLES
                      totalCost = 
                      numMonths =
 		
 		costMonth = totalCost/numMonths;
 		return costMonth;
 	}
 }

Thanks.

It would help to see the math involved. That is, based on the variable names it is a bit tough to determine the algorithm to use. The biggest thing I don't know is the length of time in months. We need a start month and year if you want to compare it to, for example, today.
But totalCost might be something like:

Code:

totalCost = downPay + monthPay * numMonths;  // again, this has to be figured out
 
 if( milesDriven > maxFreeMiles )
     totalCost += (milesDriven - maxFreeMiles ) * overMaxMiles;

This should be better:

Code:

public double getcostperMonth()
 	{
 		double totalCost;
 		double numMonths;
 		double costMonth;
 		
 		totalCost = downPay + (monthPay * termLease);
  		totalCost += (milesDriven - maxFreeMiles ) * overMaxMiles;
 		double costperMonth = totalCost / termLease;
  
 		return costperMonth;
 		
 	}

Greetings.
