Daily Term: Immutable Object

Immutable Object

An Immutable Object is an object whose state cannot be modified after it’s created, making it inherently thread-safe. For example, in Java, the String class is immutable—any modification creates a new String. Immutability simplifies concurrency by eliminating the need for synchronization, as threads can safely share immutable objects, but it can lead to increased memory usage due to creating new objects for each change.
