how to sort List objects based on the object fields in Scala?

I have a List of objects(for example, Student(Name: String, RollNo: Int)) and is there a way to sort them in Scala?

Thanks in advance.

You can do this:

case class Student(name: String, rollNo: Int)

val list = List(Student("bbb",1), Student("aaa",1))

val sortedList = list.sortBy(_.name)

or choose the rollNo property.

You can use sortWith() function or Ordered trait to sort the List objects. check out the below link:
