Explanation / Answer

public class Account { protected Customer customer; protected double balance; protected int accountNumber = 23020 ; protected String accountType; static Transaction[] transaction = new Transaction[20];
//reallocate method to double the size of the array public Transaction[] reallocate(Transaction[] transaction){ Transaction[] trans = new Transaction[transaction.length * 2]; for (int i =0; i< transaction.length; i++ ){ trans[i] = transaction[i]; } return trans; }


public Account(Customer customer, double balance) { super(); this.customer = customer; this.balance = balance; this.accountNumber =accountNumber; }


// method getBalance() public double getBalance() { return balance; } // method getCustomer() public Customer getCustomer() { return customer; } // method setCustomer() public void setCustomer(Customer customer) { this.customer = customer; } public int getAccountNumber() { return accountNumber; }
public void setAccountNumber(int accountNumber) { this.accountNumber = accountNumber; }


public String getAccountType() { return accountType; }


public void setAccountType(String accountType) { this.accountType = accountType; }


//method toString @Override public String toString() { return "Account [Account number= "+ getAccountNumber()+", Account type ="+getAccountType()+" Balance=" + getBalance() + ", getCustomer()=" + getCustomer() + "]"; } }
