What are mutable and immutable data types give two examples of each?

Simple put, a mutable object can be changed after it is created, and an immutable object can't. Objects of built-in types like (int, float, bool, str, tuple, unicode) are immutable. Objects of built-in types like (list, set, dict) are mutable. Custom classes are generally mutable.

Which of the following is an mutable as well as ordered collection?

Which one of the following is mutable data type? Explanation: set is one of the following is mutable data type. Which of following types is mutable? Objects of built-in types like (int, float, bool, str, tuple, unicode) are immutable. Objects of built-in types like (list, set, dict) are mutable. Custom classes are generally mutable.

Regarding this, what are immutable types?

An immutable type, in the context of C#, is a type of object whose data cannot be changed after its creation. An immutable type sets the property or state of the object as read only because it cannot be modified after it is assigned during initialization. Immutable types provides higher security than mutable types. Is a tuple mutable or immutable? A tuple is a sequence of values much like a list. The values stored in a tuple can be any type, and they are indexed by integers. The important difference is that tuples are immutable.

Then, how do you know if a class is mutable?

To properly define mutable and immutable classes, one must first define what it means for an object instance to be mutable. An object instance is mutable if there is any possible(*) means via which the state encapsulated thereby might be modified. An object instance is immutable if its state cannot possibly be changed. People also ask how do you make a class mutable? Make all mutable fields final so that their values can be assigned only once. Initialize all the fields through a constructor doing the deep copy. Perform cloning of objects in the getter methods to return a copy rather than returning the actual object reference. Don't provide methods that modify the mutable objects.
