General Class VS Data Class in Kotlin

Some main difference between them:

· Data class provides those — toString(), hashCode(), copy(), component(), equals().

· Data class can’t be extended. They are final by default.

· Provides self-generated(boilerplate) code.

· Data class contain only state, doesn’t perform any operations.

· If I have a class that is just meant to store data and not perform any operations, then I’ll use a data class to simplify my code.

· A data class must be declared with at least one primary constructor parameter which must be declared with val or var. A normal class can be defined with or without a parameter in its constructor.

· Data class only deals with data.
