Read MoreDifference between mutable and immutable object
In Java, state of the immutable object can’t be modified after it is created but definitely reference other objects. They are very useful in multi-threading environment because multiple threads can’t change the state of the object so immutable objects are thread-safe. Immutable objects are very helpful to avoid temporal coupling and always have failure atomicity and also helpful in multiple threading. Why though? because no one can change the object right? So, it becomes thread-safe, it means it will not cause any unexpected issues when different parts of the program are trying to access that particular object. On the other ...
