Description: Immutable refers to an object that cannot be modified after it has been created. This concept is fundamental in programming and software design, as it promotes data security and integrity. By using immutable objects, the possibility of unexpected changes in an object’s state is avoided, which can lead to hard-to-trace errors. In programming languages such as Java, C#, and Python, immutable objects are common and are used to represent data that should not change throughout its lifecycle. For example, strings in Java are immutable, meaning that any operation that seems to modify a string actually creates a new string. This feature allows for performance optimization and memory management, as immutable objects can be shared across different parts of a program without the risk of alterations. Additionally, in the context of functional programming, immutability is a key principle that helps create more predictable and understandable code, facilitating parallelization and concurrency in complex applications.
