Bank account gui using composition BankAccount and CPerson with array of 10

[chris olejniczak]

here is everything I have so far I don't know how to implement these two classes with the array of 10 and get them into the gui fields properly. If anyone can help I would appreciate it I tried asking my teacher for help and he really didn't give me a straight answer he talked me in circles.

class BankAccount
{
        int accnum;
        static int amount;
		private static double withdraw;
        CPerson person;
        
        public int getAccnum() {
			return accnum;
		}
		public void setAccnum(int accnum) {
			this.accnum = accnum;
		}
		public static int getAmount() {
			return amount;
		}
		public void setAmount(int amount) {
			this.amount = amount;
		}
		BankAccount(int num,int amt,String nam,int ag)
        {
                accnum=num;
                amount=amt;
                person = new CPerson("",0);
        }
        public void deposit(int amt)
        {
                amount=amount+amt;
        }
        public void withdraw(int amt) throws FundsInsufficientException
        {
                if(amt>amount)
                        throw new FundsInsufficientException(amount,amt);
                else
                        amount=amount-amt;
        }
		public static double getWithdraw() {
			return withdraw;
		}
		public static void setWithdraw(double withdraw) {
			BankAccount.withdraw = withdraw;
		}
}

You have already built the GUI. What happens when you run it? You need to explain a bit more on what you need.

I also see frequent loops being used, but, you then refer to the array items with hardcoded index. In that case, you don't need the loop.

[L Sankaranarayanan]

Two things you should do
STEP1 .You should instantiate an Account object at the beginning as shown below

import javax.swing.*;  
public class BankGui {  
JTextField text[];  
JButton deposit,withdraw,exit,clear;  
JLabel label[];  
BankAccount bank;
BankGui(BankAccount bank){  
    text = new JTextField[4];  
    label = new JLabel[4];  
this.bank = bank;

STEP 2: Change actionListener method as follows

  withdraw.addActionListener(new ActionListener() {  
        public void actionPerformed( ActionEvent e) {  
          
            double wd = Double.parseDouble(text[1].getText());  
            bank.withdraw(wd)// call this method
          // double wdamount = BankAccount.getWithdraw() - wd;  
            //BankAccount.withdraw(wdamount);  
           //wd = wdamount;  
            text[3].setText("Balance: " +bank.amount-wd);  
             
              
                       
             }  
          
    })

There is another easy way .We can define our business logic in the BankAccount class by writing a method

 public double getBalance()
{
return (amout-withdraw);
}
