In Java, a mutable class is a class whose instances can be modified after they are created. It means that the state of the object can change through various methods and operations during its lifetime. Unlike immutable classes, where instances are fixed upon creation and cannot be modified, mutable classes offer flexibility and dynamic behavior.
Jul 9, 2024 · Mutable class objects provide methods to modify their content, whereas immutable class objects do not allow state modification. Mutable class objects may or may not be thread-safe, while immutable class objects are inherently thread-safe. Creating a new object is required when modifying the state of an immutable class object, while mutable ...
Feb 6, 2024 · Conclusion. In conclusion, the choice between mutable and immutable objects in Java plays a crucial role in shaping the reliability, efficiency, and maintainability of your code. While immutability provides thread safety, predictability, and other advantages, mutability offers flexibility and dynamic state changes.

Nov 2, 2018 · If a class type is mutable, a variable of that class type can have a number of different meanings. For example, suppose an object foo has a field int[] arr, and it holds a reference to a int[3] holding the numbers {5, 7, 9}. Even though the type of the field is known, there are at least four different things it can represent:
Strings can be mutable or immutable depending on the language. Strings are immutable in Java. Any time you change a string (e.g.: tacking on an extra character, making it lowercase, swapping two characters), you're actually creating a new and separate copy:
In simple terms, when working in Java, deciding between mutable and immutable objects is very important as it affects how reliable, efficient, and maintainable your code will be. Immutable objects ensure thread safety, predictability, and other benefits. Mutable objects, on the other hand, provide flexibility and allow for dynamic state changes.
