Mortgage Calculator help

[SplinteredChaos]

I'm closing my 6th week of Java programming and I feel like I'm riding on a roller coaster. Some parts come real easy and make sense, others I struggle mightily with. I've got an assignment that was due a few days ago and I'm struggling with it, to get it to function the way I need it to. I've managed to get the internal errors, cannot find symbols and all that jazz to all but disappear, but I'm at a loss on how to move on to the next step. Below is the code I have (main class and storage class). I get

"Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - cannot find symbol
symbol: constructor MortgageStorage(java.lang.String,java.lang.String,double,double)
location: class it215mortgagecalculator2point1.MortgageStorage
at it215mortgagecalculator2point1.it215mortgagecalculator2point1.main(it215mortgagecalculator2point1.java:80)
Java Result: 1"

upon completion of the last iteration of the array.

On line 80 I have a flag showing in Netbeans that prompts me to create a constructor in the storage class. If I let Netbeans create the constructor the error above still shows up. The constructor that Netbeans puts in to the storage class is

 MortgageStorage(String firstname, String lastname, double lAmount, double iRate) {
        throw new UnsupportedOperationException("Not yet implemented");
    }

Any help in pointing me on how to resolve things would be greatly appreciated!! Here's the code for the main class

 package it215mortgagecalculator2point1;

/*

import java.util.Scanner;

package it215mortgagecalculator2point1;

/**

public class it215mortgagecalculator2point1 {
    private static double termInyears;
    private static int s;

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args)
    {
        Scanner input = new Scanner(System.in);
        String firstname = null;
        String lastname = null;
        double lAmount = 0;
        double iRate = 0;
        int termInYears = 0;

        MortgageStorage[] ms = new MortgageStorage[2];

        for (double s = 0; s<ms.length; s++)
{

            System.out.println("Please enter your first name: ");
            firstname = input.next();
            while (firstname.equals(" "))

{
System.out.println("You must enter a first name");
firstname = input.next();

                        }
System.out.println("Please enter your last name:");
lastname = input.next();
while (lastname.equals(" "))

{
System.out.println("You must enter a last name:");
lastname = input.next();

}
System.out.println("Please enter the loan amount: $");
lAmount=input.nextDouble();
while(lAmount<1)

{
System.out.println("You must enter a positive value for the amount of the loan.");
lAmount=input.nextDouble();

}
System.out.println("Please enter the interest rate of the loan (eg.5.0)");
iRate=input.nextDouble();
while(iRate<1)

{
System.out.println("You must enter a positive value for the interest rate");
iRate=input.nextDouble();

}
       System.out.println("Please enter the term of the loan in years");
            termInYears=input.nextInt();
while(termInYears<1)
{
        System.out.println("You must enter the number of years of the loan");
            termInYears=input.nextInt();
                        }
        }
            ms[s]=new MortgageStorage(firstname, lastname, lAmount, iRate);


        System.out.printf("Name: " + ms[s].getfName());
        System.out.println("Name: "+ ms[s].getlName());
        
        System.out.println();
    }
}

	
	
and the storage class
