# Account Class

Your task is to design a class named `Account` that represents a basic bank account. The `Account` class will hold information about the account holder's name, account number, and balance. Additionally, you will implement methods to manipulate these details safely and effectively.

### Requirement

Account class should contain:&#x20;

**Instance Variables:**

* `accountHolder`: a `String` representing the name of the account holder.
* `accountNumber`: a `String` representing the account number.
* `balance`: a `double` representing the current balance of the account.

**Constructor:**

The constructor should contain THREE parameters to initialize all instance variables.

**Accessor Methods (Getters):**

* `getAccountHolder()`: returns the account holder's name.
* `getAccountNumber()`: returns the account number.
* `getBalance()`: returns the current balance.

**Mutator Methods (Setters):**

* `setAccountHolder(String name)`: sets the account holder's name.
* `setAccountNumber(String number)`: sets the account number.



**Additional Methods:**

* `boolean deposit(double amount)`: adds the specified amount to the balance. The method should return a boolean value, indicating deposit success or failure. If amount is positive, return true; otherwise return false.
* `boolean withdraw(double amount)`: subtracts the specified amount from the balance. **The method should return true is sufficient funds are available**. If not, the balance remains unchanged, and the method should return false.



The following table contains a code execution sequence and the corresponding results:

### Your task

Your task is to implement the `Account` class in Java and then test it in the main method **using the 👆provided execution table**. 👆&#x20;

URL: [https://www.onlinegdb.com/classroom/Fd0aduv55](https://www.onlinegdb.com/classroom/Fd0aduv55)

**If the expression has return value, PRINT IT.  That's how your pass the test.**



You need to pass the test to submit.&#x20;



**Example Solution(credit to Sherry Liao):**

```java
public class Main{

    public static void main(String[] args){
        Account a1 = new Account("John Doe", "12345678", 100);
        System.out.println(a1.getBalance());
        System.out.println(a1.deposit(50));
        System.out.println(a1.getBalance());
        System.out.println(a1.withdraw(20));
        System.out.println(a1.getBalance());
        System.out.println(a1.getAccountHolder());
        System.out.println(a1.getAccountNumber());
        a1.setAccountHolder("Jane Smith");
        System.out.println(a1.getAccountHolder());
        System.out.println(a1.withdraw(150));
        System.out.println(a1.getBalance());
        System.out.println(a1.deposit(-10));
        System.out.println(a1.getBalance());
        
    }
}
```

```java
class Account{
    private String accountHolder;
    private String accountNumber;
    private double balance;
    public Account (String holder, String num,double ba){
        accountHolder=holder;
        accountNumber=num;
        balance=ba;
    }
    public String getAccountHolder(){
        return accountHolder;
    }
    public void setAccountHolder(String name){
        accountHolder =name;
    }
    
    public String getAccountNumber(){
        return accountNumber;
    }
    public void setAccountNumber(String number){
        accountNumber =number;
    }
    
    public double getBalance(){
        return balance;
    }
    public  boolean deposit(double amount){
       if (amount >0){
           balance+=amount;
           return true;
       }
       return false;
   }
    public boolean withdraw(double amount){
        if (amount<=balance){
            balance-=amount;
            return true;
        }
        return false;
    }
    
}
```
