Hi everyone i have this simple banking program here and i was hoping someone could help me jazz it up.. Something simple like making it easier to use or making it look better. Just trying to go beyond what was asked for..
import javax.swing.JOptionPane;
class MiniLab5z
{
public static double newBalance=0;
public static double balance=0;
public static double adjustment=0;
public static String response;
public static String moreBankingBusiness;
public static void main(String[] args)
{
try
{
moreBankingBusiness = JOptionPane.showInputDialog("Do you want to do some banking?");
moreBankingBusiness=moreBankingBusiness.toUpperCase();
}
catch (Exception e)
{
// Print out the exception that occurred
System.out.println("Invalid Button Press - "+e.getMessage());
System.exit(0);
}
while(moreBankingBusiness.equals("YES"))
{
try
{
response=JOptionPane.showInputDialog
("What would you want to do ?\n1.Deposit\n2.Withdraw\n3.GetBalance");
if(response.equals(""))
{
JOptionPane.showMessageDialog
(null,"You nust make an entry in the InputBox.");
System.exit(0);
}
if(response==null)
{
JOptionPane.showMessageDialog(null,"You clicked on the Cancel button.");
System.exit(0);
}
int ch = Integer.parseInt(response);
switch (ch)
{
case 1:
deposit();
break;
case 2:
withdrawal();
break;
case 3:
balance();
break;
default :
JOptionPane.showMessageDialog(null,response+" is not vaild banking function");
break;
}
balance=newBalance;
moreBankingBusiness=JOptionPane.showInputDialog("Do you have more banking business?");
moreBankingBusiness=moreBankingBusiness.toUpperCase();
}
catch (Exception e)
{
// Print out the exception that occurred
System.out.println("Invalid type of Input or Button Pressed - "+e.getMessage());
System.exit(0);
}
}//end of while
}
public static void deposit()
{
try
{
adjustment=Double.parseDouble(JOptionPane.showInputDialog("Enter the Deposit Amount"));
newBalance=balance+adjustment;
JOptionPane.showMessageDialog(null,"***SMILEY NATIONAL BANK***\n\n"+
"Old Balance is:"+balance+"\n"+"Adjustment is :"+adjustment+"\n"+
"New Balance is:"+newBalance+"\n");
}
catch (Exception e)
{
// Print out the exception that occurred
System.out.println("Invalid operation - "+e.getMessage());
System.exit(0);
}
}
public static void withdrawal()
{
try
{
adjustment=Double.parseDouble(JOptionPane.showInputDialog("Enter the Withdrawal Amount"));
if (balance-adjustment>=0)
{
newBalance=balance-adjustment;
JOptionPane.showMessageDialog
(null,"***SMILEY NATIONAL BANK***\n\n"+
"Old Balance is:"+balance+"\n"+
"Adjustment is :"+adjustment+"\n"+
"New Balance is:"+newBalance+"\n");
}
else
JOptionPane.showMessageDialog
(null,"***SMILEY NATIONAL BANK***\n\n"+
"Insufficient funds to withdraw.");
}
catch (Exception e)
{
// Print out the exception that occurred
System.out.println("Invalid operation - "+e.getMessage());
System.exit(0);
}
}
public static void balance()
