Transaction

  Asked By: Anpu    Date: Nov 15    Category: Java    Views: 548
  

well i need to create a class called Transaction, this class purpose
is to store data for individual transactions. it also needs to
reference to the account object that i have which will be affected by
the transaction, amount of the transaction. so like when some one
takes money out of a cheque account they are hit with a 10 cent fee
wich is debited from thier account,
or when its a eftcard account that they have taken money out of their
account it is ckecked to see if they have a balance of $500,000 or
less they have a interest rate of 3% but if its 4% if its over
500,000.
well this to me is a bit confusing so please what whould i need to do?

my other classes that are included

private String accType = "";
private String accNo = "";
private double balance;
private double intRate= 0.0;




//constructors to initialise all varibles
// of the account


Account (){}

// } // this the end of the initialising of the first constructor


//constructors set parameters of the account


Account (String aType, String aNo, double aBal, double aRate ){
accType = aType;
accNo = aNo;
balance = aBal;
intRate = aRate;


} // this the end of the initialising of the second constructor


// setting the set methods to assign values

public void setAccType(String a) {
accType = a;
}

public void setAccNo(String a) {
accNo = a;
}

public void setBalance(double a) {
balance = a;

}
public void setIntRate(double a) {
intRate = a;
}


//settig the get methods to return the values

public String getAccType() {
return accType;
}

public String getAccNo() {
return accNo;
}

public double getBalance() {
return balance;
}

public double getIntRate() {
return intRate;
}

} // end of Account class

***********************************************

public class EFTCard extends Account {

// constructor that'll initialise n set parameters

EFTCard () { }

//constructor that will use the super class and set the values

EFTCard (String aType, String aNo, double aBal, double aRate ){
super (aType, aNo, aBal, aRate);


} // end of constructor initialise n set parameters

}


**************************************************************
public class Cheque extends Account {


//could have a private string for withdrawal so check that will need
//i could put it in the transaction class


// constructor that'll initialise n set parameters

Cheque () { }

//constructor that will use the super class


Cheque(String aType, String aNo, double aBal, double aRate ){
super(aType, aNo, aBal, aRate);


//should i have this for the set the interest rate to 2%
//public void setIntRate(double a) {
this.setIntRate(0.02);



} // end of constructor initialise n set parameters

****************************************************************


hey i have done a bit of code on the interface

if (obj == btnAddData) {

//this if for when user enters a transaction amount

if (txtTranxAmount.getText().equals("")){
double TrnAmt = Double.parseDouble(txtTranxAmount.getText());

if (accountType.getSelectedCheckbox().getLabel().equals("Cheque")) {
Cheq.setBalance(Cheq.getBalance() + TrnAmt )

} else{

if (accountType.getSelectedCheckbox().getLabel().equals("EFTCard")) {
Eft.setBalance(Cheq.getBalance() + TrnAmt )

}//end of the if it was eftcard


if ((Cheq == null) && (Eft == null ))

System.out.println("NO AMOUNT WAS ENTERED FOR A TRANSACTION");
// no AMOUNT WAS ENTERED FOR A TRANSACTION





//this if statement is here so is a user wants to create a an account
they must enter a clientno
if (! txtClientNo.getText().equals("")) {



Clt = new Client(txtClientNo.getText(), txtFirstname.getText(),
txtSurname.getText(), txtClientAge.getText());


if (accountType.getSelectedCheckbox().getLabel().equals("Cheque")) {

double InterestRate = Double.parseDouble(txtInterestRate.getText());
double AccountBalance = Double.parseDouble(txtAccountBalance.getText
());

Acc = new Cheque(promptAccType.getText(),txtAccountNo.getText(),
AccountBalance, InterestRate);

} else {


if (accountType.getSelectedCheckbox().getLabel().equals("EFTcard")) {

double InterestRate = Double.parseDouble(txtInterestRate.getText());
double AccountBalance = Double.parseDouble(txtAccountBalance.getText
());

Acc = new EFTCard(promptAccType.getText(),txtAccountNo.getText(),
AccountBalance, InterestRate);


} // THIS closes the if statement of the if equals bit

Brh = new Branch (branchArray[availableBranches.getSelectedIndex
()].getBranchName(),
branchArray[availableBranches.getSelectedIndex()].getBranchCode());

}

} else {

System.out.println("PLEASE ENTER A CLIENT NUMBER");
// no client number

}


} // end of if for btnAddData
