What are the main advantages and disadvantages of using data class in your project?

Data class in Android (Kotlin) provides a convenient way to create classes for storing data with automatic generation of equals(), hashCode(), toString(), and copy() methods.

Advantages:

• Less boilerplate code, which simplifies maintenance.
• Convenience of copying objects with modifications to some fields via copy().
• Clear representation of data structure.

Disadvantages:

• Not suitable for classes with logic, as data classes are intended specifically for data storage.
• Changing the structure of a data class may require data migration.

Example:

data class User(val id: Int, val name: String)

val user1 = User(1, "Alice")
val user2 = user1.copy(name = "Bob")
println(user2) // User(id=1, name=Bob)
