class ExampleClass {
    fun printDetails(firstName: String = "John", lastName: String = "Doe", yearsOfExperience: Int = 5) {
        println("First name: $firstName, Last name: $lastName, Years of experience: $yearsOfExperience")
    }

    fun myMethod() {
        printDetails() // uses default values
        printDetails("Bob", "Johnson", 5) // classic Java way
        printDetails(firstName = "Bob", yearsOfExperience = 10) // with named params, some can be skipped
        printDetails(lastName = "Johnson", yearsOfExperience = 7, firstName = "Bob") // order can be switched
    }

    fun doStuff(
        name: String = "John",
        greeting: String = "$name, welcome home!" // you can access other params' values like this
    ) {
        // ...
    }
