如何从数据类中获取/设置任何字段的值？(在Kotlin中)

data class Person(val name: String, val age: Int)

fun main() {
    val person = Person("John", 25)
    val personClass = person.javaClass

    val nameField = personClass.getField("name")
    val ageField = personClass.getField("age")

    val nameValue = nameField.get(person)
    val ageValue = ageField.get(person)

    println("Name: $nameValue")
    println("Age: $ageValue")
}

data class Person(var name: String, var age: Int)

fun main() {
    val person = Person("John", 25)
    val personClass = person.javaClass

    val nameField = personClass.getDeclaredField("name")
    val ageField = personClass.getDeclaredField("age")

    nameField.isAccessible = true
    ageField.isAccessible = true

    nameField.set(person, "Jane")
    ageField.set(person, 30)

    println(person)
}
