Anyone can help me to link this test: A

class Rectangle {
    val width: Int
    val length: Int

    constructor(_width: Int, _length: Int) {
        width = _width
        length = _length
    }
}

val rectangle = Rectangle()

B

class Rectangle {
    val width: Int
    val length: Int

    constructor(width: Int, length: Int) {
        width = width
        length = length
    }
}

C

class Rectangle {
    val width: Int
    val length: Int
    
    constructor(_width: Int, _length: Int) {
        width = _width
        length = _length
    }

    constructor(_sizeA: Int, _sizeB: Int) {
        width = _sizeA
        length = _sizeB
    }
}

D

class Rectangle {
    val width: Int
    val length: Int

    constructor(width: Int, length: Int) {
        
    }
}

E

class Rectangle {
    val width: Int = 1
    val length: Int = 1

    constructor(width: Int, length: Int) {
        this.width = width
        this.length = length
    }
}

F

class Rectangle() {
    var width: Int = 1
    var length: Int = 1

    constructor(width: Int, length: Int) {
        this.width = width
        this.length = length
    }
}

I am a bit confused 🧐 1. Signature uniqueness violation 2. Primary constructor call is absent 3. Reassigning previously 4. Uninitialized properties 5. No values passed for constructor pararmeters 6. Reassigning val because of name collision

Why don't you just try it, for example on play.kotl.in? Should be A - 5 B - 6 C - 1 D - 4 E - 3 F - 2

I know that's a technical test to grasp the syntax, but I don't understand the point of this question ... every Kotlin developer would have written

class Rectangle(val width: Int, val length: Int)

Probably to gather insight. Test questions are seldomly related to real code.

@Vampire thanks for the answer, I didnt know I could run this code in play.kotl. Again, thanks!

But better understand why the pairs are like they are 😉

Definitely, I am into it.
