I would like to know if by how, by Javadoc know whether a class is immutable or not. There is some field in Javdoc for quick query, as I am using several classes and do not have much contact with the language. I would like the answer and, if possible, an image. Thank you. I’m working with shapes. It would be nice if this class were used as an example.

You should look at whether the constructor is private, it is generally recommended to use it privately and create a public method of() that returns a new object. If she has setters, if she doesn’t have you you won’t be able to change values.

  • A class can be immutable and have public constructor. See for example String.

  • You can! I’ll adjust the answer.
