Answer 1

public class BankAccount {

//private data members, means accessible to only this class

private int accountNumber; // Holds account number of user

private String ownerName; // Holds name of user

private double balance; // Holds total balance in account

private String type; // Personal, business, Charitable

// Default constructor

// This constructor initializes data members with some default values

public BankAccount() {

accountNumber=0;

ownerName="";

balance=0.0;

type="Personal";

}

// Parameterized constructor

// This constructor initializes data members with values passed in arguments

public BankAccount(int number, String name, double initialDeposit, String type) {

accountNumber = number; // Sets account number with number

ownerName = name; // Sets owner name with name

balance = initialDeposit;// Set balance with initial deposit

// Here, this is used because the variable name of data member and parameter is same

// "this" here refers to the current object for which the constructor is called

this.type = type; // Sets type with passed value type

}

// Getter method which returns account number

public int getAccountNumber() {

return accountNumber;

}

// Setter method which can be used to set a new account number

public void setAccountNumber(int number) {

accountNumber = number;

}

// Getter method which returns owner name

public String getOwnerName() {

return ownerName;

}

// Setter method which can be used to set a new owner name

public void setOwnerName(String name) {

ownerName = name;

}

// Getter method which returns balance in account

public double getBalance() {

return balance;

}

// Setter method which can be used to set new balance

public void setBalance(double newAmount) {

balance = newAmount;

}

// Getter method which returns tyoe of account

public String getType() {

return type;

}

// This method add passed amount to balance and updates balance

public void deposit(double amount) {

balance+=amount;

}

// This method subtract passed amount from balance and updates balance

public void withdrawal (double amount) {

balance -=amount;

}

// This method returns a string with following details -

// type : accountNumber ownerName balance

// Example - Personal: 12345 Max 25000

public String ToString() {

return type + ": " + accountNumber + " " + ownerName + " " + balance;

}

}
