Java Code for a project

Instructions
Description:
This activity will help you reinforce what you've learned about objects, classes and constructors and provide practice reading and implementing code in Java. Your goal is to complete implementation of the Patient class and verify the functionality using the Main class.

Please follow the steps below:

Steps:
Add the following code to the 'Bill.java' file:
class Bill {

private double amount;
private String date;

public Bill(double amount, String date) {
this.amount = amount;
this.date = date;
}

public double getAmount() {
return amount;
}
public void setAmount(double amount) {
this.amount = amount;
}

@Override
public String toString() {
return "Billing date: " + this.date + ". Bill amount: " + this.amount;
}

}
This class allows us to create Bill objects. It defines the following:

two private instance variables, amount and date
a parameterized constructor that initalizes amount and date using the parameter values
a getter and setter for amount
and an overridden toString() method
Now you'll create a Patient class. In Patient.java, create a class that defines the following:
2 private instance variables of the String type called name and illness
1 private instance variable of the type ArrayList<Bill> with the name bills (make sure to import the ArrayList class from the java.util package)
a parameterized constructor that takes two values. The first should be a String parameter to initialize the field name. The second parameter should be an ArrayList<Bill> to initialize the field bills.
getters and setters for name and illness
a method named addBill() that takes in a parameter of the Bill type and adds the bill to the list bills using the add() method for ArrayList objects.
an overridden toString() method that returns the following String: "[Patient's name = " + name + ", Patient's illness = " + illness + "]";
a method named printBills() that prints the total value of all bills. Use the following as a guide to create this method:
create a total variable of type double and assign it an initial value of 0.
use a for-each loop to iterate over bills: for each bill, add the bill's amount to the total.
Then, still within the for-each loop, print the bill to the console using the println() method
print the total value after the loop ends
Let's test out your Patient class. In the main() method, perform the following tasks:
create an ArrayList of the Bill type and save it into a variable
create a new patient with the name John and the ArrayList you just created
set John's illness to severe cold and print the patient to the console
create a new Bill object for John with the amount 99.95 and the date June 15 2021
add the bill to John's list of bills using the appropriate method
print all of John's bills using the appropriate method
Test:
Use the test provided.

Sample output:
[Patient's name = John, Patient's illness = severe cold]
Billing date: June 15 2021. Bill amount: 99.95
99.95
