Thank you for sharing these helpful libraries.

[@Anbu_Sampath]

RecordBuilder seems interesting library.

[@salithachathuranga6037]

Lombok library provides record builder functionality. It is way more used in the industry in enterprise level.

[@sivalabs]

Yes, Lombok is a widely used library and I too have used it extensively (www.sivalabs.in/should-you-use-lombok-or-is-it-bad-for-you/). I never had any trouble while using Lombok alone, but when used it with other annotation processors like MapStruct, AutoValue then there are some issues.

Regarding MapStuct, does it support expression/ conditional kind of conversion?
Like suppose, I have a wrapper class Boolean in Entity. But I want to pass primitive boolean to DTO. Expression will be
flag == null ? false : true
flag is wrapper Boolean class in Entity.

[@sivalabs]

Yes, it checks for null and assign the correct value as follows:
boolean active = false;
if ( user.active() != null ) {
active = user.active();
}
UserDTO userDTO = new UserDTO( id, fullName, emailAddress, active );
