What is the mutability of collections in programming languages?
Mutability refers to whether a collection can be changed after it is created. In programming, collections like lists, sets, and dictionaries can be mutable or immutable.
Can you give examples of mutable and immutable collections?
Sure! In Python, lists and dictionaries are mutable, while tuples and strings are immutable. In Java, ArrayLists are mutable, but arrays are fixed in size.
Why is mutability important in programming?
Mutability affects performance, memory usage, and the ability to modify data structures. It can also impact the design of algorithms and data integrity.
How does mutability affect concurrency in programming?
Mutable collections can lead to issues in concurrent programming, such as race conditions. Immutable collections are often safer in multi-threaded environments.
