Kuidas tagatakse andmete terviklikkus objekti sees selle kasutamise või muutmise ajal?

Data integrity within an object during use or modification is ensured by several methods:

• Encapsulation — hiding the internal data of the object and providing access only through methods that control the correctness of changes.

• Use of properties with checks in setters to prevent incorrect values.

• Immutability — creating immutable objects where data does not change after initialization, preventing unintentional modifications.

• Synchronization of access in multithreaded environments using locks (lock, mutex) to prevent race conditions and ensure atomic operations.

Example in C# using a property and validation:

class Person
{
    private int age;
    public int Age
    {
        get => age;
        set
        {
            if (value < 0 || value > 150)
                throw new ArgumentOutOfRangeException("Age must be between 0 and 150");
            age = value;
        }
    }
}

This way, the object controls the correctness of its data and protects it from incorrect modifications.
