    Good question, you can tell us why you think something is missing?

  • Please rephrase the question so we know what your question is.

  • The following error appears: source.kt:4:23: error: unresolved Reference: Task val minhaTarefa = Task("Daniel", "Programming", 10, "September 30") ^

  • But I don’t know what I need to do to fix it, you can help me?

    Apparently there is no class called Tarefa.

  • The class name is wrong, try as val minhaTarefa = TarefaDeCasa("Daniel", "Programação", 10, "30 de Setembro")

    That’s exactly what it was!!! Thank you guys so much! I managed to make the code!

There is no class called Tarefa, the class name is TarefaDeCasa

fun main(args: Array<String>) {
    val minhaTarefa = TarefaDeCasa("Daniel", "Programação", 10, "30 de Setembro")

    minhaTarefa.entregar()
}

class TarefaDeCasa(
    var nomeDoAluno: String,
    var nomeDaMateria: String,
    var nota: Int,
    var dataDeEntrega: String) {

    fun entregar() {
        println("o aluno ${nomeDoAluno} entregou a tarefa do dia ${dataDeEntrega} e recebeu a nota ${nota}")
    }
}

See working in Try.kotlinlang.org

So it works, I think it was just typo since the created class calls TarefaDeCasa and the call to instantiate was Tarefa:

fun main(args: Array<String>) {
    val minhaTarefa = TarefaDeCasa("Daniel", "Programação", 10, "30 de Setembro")
    minhaTarefa.entregar()
}
class TarefaDeCasa(
    var nomeDoAluno: String,
    var nomeDaMateria: String,
    var nota: Int,
    var dataDeEntrega: String) {

    fun entregar() {
        println("o aluno ${nomeDoAluno} entregou a tarefa do dia ${dataDeEntrega} e recebeu a nota ${nota}")
    }
}

Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.
