To see my progress on this project, you must select MASTER BRANCH.

[IMPORTANT NOTES] There are few classes that I actually dont use, because it is not efficient. The classes that are not used -> (Calculation.java, Drinks.java, and restaurant.java)

Applied Topic in My Program:

1. Casting/Conversion

   FP-OOP/src/Form.java

   Lines 49 to 52 in 4594325

   	burger = Double.parseDouble(nburger.getText());
   	pizza = Double.parseDouble(npizza.getText());
   	cola = Double.parseDouble(ncola.getText());
   	water = Double.parseDouble(nwater.getText());

   FP-OOP/src/Form.java

   Lines 79 to 86 in 4594325

   	String str = Double.toString(a);
   	double b = pizza * pizzadefault;
   	String str1 = Double.toString(b);
   	double c = water * waterdefault;
   	String str2 = Double.toString(c);
   	double d = cola * coladefault;
   	String str3 = Double.toString(d);
   	String str4 = Double.toString(result);

2. Constructor

   FP-OOP/src/Employee.java

   Lines 9 to 12 in 4594325

   	public Employee(String Name, String pass) {
   	this.Name = Name;
   	this.setPass(pass);
   	}

3. Overloading

   FP-OOP/src/Burger.java

   Lines 1 to 5 in 4594325

   	public class Burger extends FoodDescription{
   	public void FoodDesc() {
   	System.out.println("Burger: a flat round mass of minced meat or vegetables, which is fried and often eaten in a bread roll.\n");
   	}
   	}

   FP-OOP/src/Pizza.java

   Lines 1 to 5 in 4594325

   	public void FoodDesc() {
   	System.out.println("Pizza: dish of Italian origin consisting of a flattened disk of bread dough topped with some combination\n");
   	}
   	}

4. Overriding

   FP-OOP/src/Food.java

   Lines 10 to 21 in 4594325

   	public Food(String Name, Double Price, String Description){
   	this.Name = Name;
   	this.Price = Price;
   	this.Description = Description;
   	}
   	public Food(String Name, Double Price, String Description, Double Discount){
   	this.Name = Name;
   	this.Price = Price;
   	this.Description = Description;
   	this.Discount = Discount;
   	}

5. Encapsulation
