java - loan calculator that implements multiple methods -

i have been working on program java loan payment calculator comp sci class. programs requriements are:

1. ask user loan amount, annual interest rate, , number of months
2. call method calculate , return monthly interest rate
3. call method calculate , return monthly payments
4. call method print loan statement showing amount borrowed, annual interest rate, number of months , monthly payment.

this first time working multiple methods. have developed code far shown below. netbeans editor not giving me errors, however, not print statements last method. questions are:

1. are methods set correctly , passing parameters correctly
2. why won't statements print @ end
3. am capturing other methods correctly? need enter variables in main method , call them in final method.
4. is of code redundant?

i not sure how proceed here.

public class carloan {  /**  * @param args command line arguments  */ public static void main(string[] args) {     // declare variables main method     double loanamount;//double value loan amount      double annualinterestrate;//double value interest rate     int numberofmonths;//int value number of months     double monthlypayment;  scanner keyboard = new scanner(system.in);      system.out.println("please enter amount of loan.");     loanamount = keyboard.nextdouble();      system.out.println("please enter annual interest rate decimal. ex. 7.5% = .075");     annualinterestrate = keyboard.nextdouble();      system.out.println("please enter number of months have pay loan.");     numberofmonths = keyboard.nextint();  } *************************************************  public static double calcmonthlyinterestrate(double annualinterestrate){     double monthlyinterestrate;         monthlyinterestrate = (annualinterestrate/12);         return monthlyinterestrate; }//end method calcmonthlyinterestrate **************************************************************************************      public static double calcmonthlypayment(double monthlyinterestrate, double loanamount, int            numberofmonths     ){     double monthlypayment;     double calcmonthlypayment;         calcmonthlypayment = (monthlyinterestrate*loanamount)/(1-(1+monthlyinterestrate)-numberofmonths);         return monthlypayment = calcmonthlypayment; }//end method calcmonthlypayment ****************************************************************************************        public static void loanstatment (double loanamount, double annualinterestrate, intnumberofmonths,  double monthlypayment){  system.out.println("your loan amount " +loanamount);  system.out.println(annualinterestrate);  system.out.println(numberofmonths);  system.out.println(monthlypayment);   }    }//end main method   }//end main method 

have @ main method , see doing declaring variables , receiving input. other methods perform calculations , loanstatment (sic) method prints results never called.

i recommend read on basics waste less of time simple errors one.
