5. If we have a mutable object inside immutable class then how will you handle it?

Question

Accepted Answer

To handle a mutable object inside an immutable class, make the object private and provide only read-only access methods.

Make the mutable object private to encapsulate it within the immutable class.
Provide read-only access methods to retrieve the state of the mutable object.
Ensure that the mutable object cannot be modified from outside the class.
If necessary, create defensive copies of the mutable object to prevent unintended modifications.

Accepted Answer

We need to use Deep cloned copy of the object in the constructor and the getter method when we use a mutable object as a field in an immutable class.

Accepted Answer

If we have a mutable object inside an immutable class, we need to ensure that the mutable object cannot be modified from outside the class. Here are some ways to achieve this:

Make the mutable object private and final: We can make the mutable object private and final to prevent it from being modified from outside the class. This ensures that the reference to the mutable object cannot be changed once it is initialized. However, if the mutable object has its own mutable state, then we need to ensure that its state cannot be changed as well.
