I dont have any transaction class information so i have created one of my choice with single description field.If you have transaction class you can change the setter in the withdraw and deposit methods
Account class:
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
public class Account {
private int accId;
private String custName;
private double accBalance;
private double interestRate;
private Date createdAt;
private List<Transaction> transList=new ArrayList<>();
public Account() {
accId=0;
custName="";
accBalance=0.0;
interestRate=0;
Date dt=new java.util.Date();
createdAt=dt;
}
public Account(int id,String name,double balance,double rate){
accBalance=balance;
accId=id;
custName=name;
interestRate=rate;
Date dt=new java.util.Date();
createdAt=dt;
}
public int getAccId() {
return accId;
}
public void setAccId(int accId) {
this.accId = accId;
}
public String getCustName() {
return custName;
}
public void setCustName(String custName) {
this.custName = custName;
}
public double getAccBalance() {
return accBalance;
}
public void setAccBalance(double accBalance) {
this.accBalance = accBalance;
}
public double getInterestRate() {
return interestRate;
}
public void setInterestRate(double interestRate) {
this.interestRate = interestRate;
}
public Date getCreatedAt() {
return createdAt;
}
public void setCreatedAt(Date createdAt) {
this.createdAt = createdAt;
}
public List<Transaction> getTransList() {
return transList;
}
public void setTransList(List<Transaction> transList) {
this.transList = transList;
}
public double getMonthlyInterest(){
double inteEarned=this.accBalance*(this.interestRate/1200);
return inteEarned;
}
public void withDraw(double amt){
this.accBalance=this.accBalance-amt;
Transaction t=new Transaction();
t.setDesc("withdrawn amount of "+amt+" from "+accId+" remaining balance is "+accBalance);
transList.add(t);
}
public void deposit(double amtDepo){
this.accBalance=this.accBalance+amtDepo;
Transaction t=new Transaction();
t.setDesc("deposited amount of "+amtDepo+" to "+accId+" new balance is "+accBalance);
transList.add(t);
}
}
Transaction class;
public class Transaction {
private String desc;
public String getDesc() {
return desc;
}
public void setDesc(String desc) {
this.desc = desc;
}
}
Tester class:
public class AccountTester {
public static void main(String[] args) {
// TODO Auto-generated method stub
Account acc=new Account(1122,"George", 1000,1.5);
acc.deposit(30);//depositing 30,40,50$
acc.deposit(40);
acc.deposit(50);
acc.withDraw(5);//withdrwaing 5,4,2$
acc.withDraw(4);
acc.withDraw(2);
System.out.println("Account summary");
System.out.println("------------------------");
System.out.println("Account holders name : "+acc.getCustName());
System.out.println("Annual interest rate : "+acc.getInterestRate());
System.out.println("Account Balance : "+acc.getAccBalance());
System.out.println("Monthly interest earned : "+acc.getMonthlyInterest());
System.out.println("Transactions done");
for(Transaction t:acc.getTransList()){
System.out.println(t.getDesc());
}
}
}
