Thread: Arrays for mortgage calc

Hi can somebody please help me or give me some direction on how I am supposed to do this: Write the program in Java (without a graphical user interface) and have it calculate the payment amount for 3 mortgage loans:
* - 7 year at 5.35%
* - 15 year at 5.5%
* - 30 year at 5.75%
Use an array for the different loans. Display the mortgage payment amount for each loan.
I dont even know if I am even close with the arrays but I think I need to add formulas to this to. I just am completely lost. Here is what I have. (I know I am not even close) Please help!!

package mortgagecalculator2;

/**
*
* @author
*/
public class MortgageCalculator2 {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
double loanAmount[]=new double[1];
loanAmount[0]=200000.00;

double loanLengthInMonths[]=new double[3];
loanLengthInMonths[0]=84;
loanLengthInMonths[1]=180;
loanLengthInMonths[2]=360;

double monthlyInterest[]=new double[3];
monthlyInterest[0]=5.35;
monthlyInterest[1]=5.5;
monthlyInterest[2]=5.75;


System.out.println(loanAmount[0]);
System.out.println(loanLengthInMonths[0]);
System.out.println(monthlyInterest[0]);
System.out.println(loanAmount[0]);
System.out.println(loanLengthInMonths[1]);
System.out.println(monthlyInterest[1]);
System.out.println(loanAmount[0]);
System.out.println(loanLengthInMonths[2]);
System.out.println(monthlyInterest[2]);

}

Do you need arrays to solve this problem at all? Looks like using simple math operations can give you what you need.

Yes it is required by the instructor to use arrays.
