What is the name for an object that cannot be added to (for example, a circle can only have 360 degrees; any more degrees and it is no longer merely a circle)?
I don't think there is a name for this concept.Pjpic said:What is the name for an object that cannot be added to (for example, a circle can only have 360 degrees; any more degrees and it is no longer merely a circle)?
An object that cannot be added to is called an immutable object. This means that the object's state or value cannot be changed once it is created.
Some examples of immutable objects include numbers, strings, and tuples in programming languages. In the physical world, diamonds, gold, and other precious metals are also considered immutable objects.
Objects may be made immutable for various reasons, such as maintaining data integrity, improving performance, or ensuring security. Immutable objects are also useful for creating data structures that are thread-safe and can be shared among multiple processes without the risk of data corruption.
Mutable objects, in contrast to immutable objects, can have their state or value modified after they are created. This means that their contents can change, making them less predictable and potentially causing errors in a program.
No, once an object is made immutable, it cannot be changed into a mutable one. However, it is possible to create a copy of the immutable object and make changes to the copy, effectively creating a new mutable object.
