Additionally, the IDE now correctly handles constructor annotations, and import suggestions include enum cases. Better code completion The IDE can now automatically fill out all named arguments of methods and autocomplete literal values of union types in Scala 3. Enum cases are now suggested ...
• A constructor is executed automatically whenever the objects of a class are created. • A constructor doesn’t have a return type, not even void. • We can declare more than one constructor in a class, i.e., constructors can be overloaded. These constructors differ in their parame...
