Design a class that stores the beginning balance of an account and the number of checks written. It should also have a method that returns the bank's service fee for the month.

Explanation / Answer

import java.util.*;
class bank
{
   public static void main(String args[])
   {
       double serch, ch=0,curbal, checks,net;
       Scanner o = new Scanner(System.in);

       System.out.println("Enter Current

balance of Account");
       curbal=(Double.parseDouble

(o.nextLine()));
      
       if(curbal<400)
       {
           ch=15;
       }
       System.out.println("Enter Checks

written");
       checks=(Double.parseDouble

(o.nextLine()));

       serch=cal(checks);
       net=serch+ch+10;      
       System.out.println("Bank Services

charges="+net);
       System.out.println("Bank Balance ="+

(curbal-net));

   }

   public static double cal(double c)
   {
       double cfees=0;
       if(c>0 && c<20)
       {
           cfees=c*.1;
       }

       if(c>=20 && c<=39)
       {
           cfees=c*.08;
       }

       if(c>=40 && c<=59)
       {
           cfees=c*.06;
       }

       if(c>=60)
       {
           cfees=c*.04;
       }
       return cfees;
   }
}
