title: loan calculator that implements multiple methods
body: <p>I have been working on a program that is a Java loan payment calculator for my comp sci class.  The programs requriements are:</p>
  
  <ol>
  <li>ask user for loan amount, annual interest rate, and number of months</li>
  <li>call a method to calculate and return the monthly interest rate</li>
  <li>call a method to calculate and return the monthly payments</li>
  <li>call a method to print a loan statement showing the amount borrowed, annual interest rate, the number of months and the monthly payment.</li>
  </ol>
  
  <p>This is my first time working with multiple methods.  I have developed the code so far as shown below.  The netbeans editor is not giving me any errors, however, it does not print the statements from my last method.  My questions are:</p>
  
  <ol>
  <li>are my methods set up correctly and passing parameters correctly</li>
  <li>why won't the statements print at the end</li>
  <li>am i capturing my other methods correctly? Do i need to enter variables in the main method and then call them in the final method.</li>
  <li>is any of my code redundant?</li>
  </ol>
  
  <p>I am not really sure how to proceed from here.  </p>
