[Solved] Sports team model – constructor in class cannot be applied to given types

Question

Explanation

Your error message is pretty straightforward, carefully read it:

Error on line 12: constructor Game in class Game cannot be applied to given types;
return r.toString() + "\n" + super.play(new Game()) + "\n";
                                        ^
required: java.lang.String found: no arguments

reason: actual and formal argument lists differ in length

So you are calling new Game(), without any arguments. But the constructor in that class requires you to call it with a String, like new Game("foo").

If you lookup the code for the class Game, you will see something like:

public class Game {
    ...

    // Constructor that requires a String as argument
    public Game(String foo) {
        ...
    }

    ...
}

Check out the class to see what exactly the purpose of that String is.

Example

To give you a better feeling for what you did wrong, let me show you another example. Suppose you have a class Person and you want that each person has a String name and an int age. You can achieve this by letting the constructor require both. For example:

public class Person {
    private final String name;
    private final int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String getName() { return name; }
    public String getAge() { return age; }
}

Now you can create instance of this class by calling the constructor and providing both, a name and an age:

Person person = new Person("John", 20);

But what you are trying to do is just calling it like new Person(), without supplying any name or age, despite the constructor requiring it.
