按类型对case类进行Scala排序

case class Person(name: String, age: Int)

val people = List(
  Person("Alice", 25),
  Person("Bob", 30),
  Person("Charlie", 20)
)

// 按年龄升序排序
val sortedByAge = people.sortBy(_.age)
println(sortedByAge)

// 按姓名降序排序
val sortedByName = people.sortWith(_.name > _.name)
println(sortedByName)

List(Person(Charlie,20), Person(Alice,25), Person(Bob,30))
List(Person(Charlie,20), Person(Bob,30), Person(Alice,25))
