🚽💦 OOP in Java & Python — The Toilet Universe
Featuring Toilet Seat, Flush Tank, Siphon & Washbasin — the funniest and most practical OOP analogy ever taught.
1️⃣ Classes & Objects
Every bathroom item becomes a class. Your bathroom becomes an object universe!
Java Version
class ToiletSeat {
String type = "Soft-Close";
boolean isUp = false;
}
class Siphon {
void suckWater() {
System.out.println("Siphon: gurgle gurgle...");
}
}
class FlushTank {
int waterLevel = 10;
Siphon siphon = new Siphon();
}
class WashBasin {
boolean isTapOpen = false;
void openTap() {
System.out.println("Water flowing...");
}
}
Python Version
class ToiletSeat:
def __init__(self):
self.type = "Soft-Close"
self.is_up = False
class Siphon:
def suck_water(self):
print("Siphon: suction activated!")
class FlushTank:
def __init__(self):
self.water_level = 10
self.siphon = Siphon()
class WashBasin:
def open_tap(self):
print("Water flowing...")
2️⃣ Encapsulation
Encapsulation hides the messy parts — like the inside of a flush tank!
class FlushTank {
private int waterLevel = 10;
private Siphon siphon = new Siphon();
public void pressButton() {
siphon.suckWater();
System.out.println("FLUSH!");
}
}
Python Version
class FlushTank:
def __init__(self):
self.__water = 10
self.__siphon = Siphon()
def press_button(self):
self.__siphon.suck_water()
print("FLUSH!")
3️⃣ Inheritance
Bathroom items can have upgraded children.
class ToiletSeat {
void sit() { System.out.println("Sitting..."); }
}
class HeatedSeat extends ToiletSeat {
void heat() { System.out.println("Heating activated!"); }
}
4️⃣ Polymorphism
One clean() method → four behaviors!
class BathroomItem {
void clean() { System.out.println("Cleaning bathroom item."); }
}
class Siphon extends BathroomItem {
@Override
void clean() { System.out.println("Cleaning siphon — wear mask!"); }
}
5️⃣ Abstraction
You push the flush button. You don’t care how the siphon bends like a cobra inside.
6️⃣ Composition
class Bathroom {
ToiletSeat seat = new ToiletSeat();
FlushTank tank = new FlushTank();
WashBasin basin = new WashBasin();
void useBathroom() {
seat.sit();
tank.pressButton();
basin.openTap();
}
}
