JAVA PROGRAM

Lab5 Implement Account, Transition classes and Add GUI to it.

Account

#name : string transactiontype

#balance : double public enum transitiontype{ deposit,withdraw;}

+ static dailywithdrawlimit :double

account ( string name, double balance) transaction

//add get, some methods for each member amount : double

// return updated balance type : transactiontype

withdraw(doubleamount) : double date : localdate

totaldepositatday(localdate dt) : double transaction(doubleamount,transactiontype t)

totalwithdrawatday(localdate dt) : double tostring() : string

totaltransactionsatday((localdate dt) : stringbuildertostring() : string

Be creative when add GUI to your project.

Minimum Requirement:A user can enter the name of the account and click create Account; Once an account is created successfully, the user can deposit, withdraw, clear Amount text field, and display all of todays transaction. Your program need do error checking and catch proper exceptions.

//add class to yoursource package, name it TransactionType

//TransactionType.java

//proper package statement

public enum TransitionType {

DEPOSIT, WITHDRAW;

}

class OverdraftExceptionextends Exception{

private double overdraftAmount;

public OverdraftException(String msg, double overAmount){

super(msg);

overdraftAmount = overAmount;

}

@Override

public String toString(){return super.getMessage() + " Overdraft amount: " + overdraftAmount;}

}

//Transition.java

import java.time.LocalDate;

import java.util.Date;

public class Transition {

LocalDate date;

double amount;

TransitionType type; //enum

public Transition(double amount, TransitionType type){

date = LocalDate.now();//current date and time

this.amount = amount;

this.type = type;

}

@Override

public String toString(){

switch(type){

case DEPOSIT:

return String.format("Deposit: $%.2f on ", amount) + date.toString();

case WITHDRAW:

return String.format("Withdraw: $%.2f on ", amount) + date.toString () ;

default:

return Error";

}

}

}

// read but do not use following Account class. Just use one ArrayList for all transactions instead of use two as in following implementation
