Immutable classes are classes whose instances cannot be modified after creation.
Immutable classes have all fields marked as final and private.
They do not have any setter methods to modify the state of the object.
Any modification to an immutable object results in a new object being created.
Example of an immutable class: public class Person { private final String name; private final int age; public Person(String n...
