Kotlin with Named and Default Argument help to write clean code

NamedDefaultArgument.kt

// Kotlin
// Default argument
fun doSomething(
  fname: String,
  lname: String,
  addr: String = "N/A",
  gender: Gender = Gender.Unknown
){
  // do something that really need fname,lname, addr, gender..
}

val firstName = "firstName"
val lastName = "lastName"
val address = "Address"
val gender = Gender.Male

// Normally you can do this
doSomething(firstName, lastName, address, gender) // OK!
doSomething(firstName, lastName, address)  // OK!
doSomething(firstName, lastName)  // OK!

// Fail, compile error! Type mismatch! Expected String type
doSomething(firstName, lastName, gender) 

// It can be solved by Named Argument
// with Named Argument
doSomething(
  fname = firstName,
  lname = lastName,
  addr = address,
  gender = gender) // OK!

// skip the address (3rd argument)
doSomething(
  fname = firstName,
  lname = lastName,
  gender = gender) // OK!

// Order is not important!!
doSomething(
  addr = address,
  lname = lastName,
  fname = firstName) // OK!

// Fail! compile error: lname is required
// because lname has no default value
doSomething(
  addr = address,
  fname = firstName)

// Ask yourself:
// Is it possible to achieve the same level of conciseness in Java?
