Private Methods: These are methods that can only be accessed within the same class. It's like an employee-only area in a store where customers cannot enter.
Static Methods: Static methods belong to the class itself rather than an instance of the class. They can be called without creating an object of that class, similar to using a vending machine without needing to own it.
Method Overloading: This is when multiple methods have the same name but different parameters. It's like having different flavors of ice cream with different toppings but all served in cones.
