Solution

public class AccountingClass
{
   private double blnce;
   private double intrst;

   public AccountingClass()
   {
       blnce = 0;
       intrst = 0;
   }

   public AccountingClass(double initialBalance, double initialInterest)
   {
       blnce = initialBalance;
       intrst = initialInterest;
   }

   public void deposit(double amnt)
   {
       blnce = blnce + amnt;
   }

   public void withdraw(double amnt)
   {
       blnce = blnce - amnt;
   }

   public void addInterest()
   {
       blnce = blnce + blnce * intrst;
   }

   public double getBalance()
   {
       return blnce;
   }

}
