Explanation<\/h2>\n

Your error message is pretty straightforward, carefully read it:<\/p>\n

\n

Error on line 12: constructor Game in class Game cannot be applied to given types;<\/p>\n

return r.toString() + \"\\n\" + super.play(new Game()) + \"\\n\";\n                                        ^\n<\/code><\/pre>\n
required<\/strong>: java.lang.String<\/code> found: no arguments<\/strong><\/p>\n
reason: actual and formal argument lists differ in length<\/p>\n<\/blockquote>\n
So you are calling new Game()<\/code>, without any arguments. But the constructor in that class requires you to call it with a String<\/code>, like new Game(\"foo\")<\/code>.<\/p>\n
If you lookup the code for the class Game<\/code>, you will see something like:<\/p>\n
public class Game {\n    ...\n\n    \/\/ Constructor that requires a String as argument\n    public Game(String foo) {\n        ...\n    }\n\n    ...\n}\n<\/code><\/pre>\n
Check out the class to see what exactly the purpose of that String<\/code> is.<\/p>\n
\n
Example<\/h2>\n
To give you a better feeling for what you did wrong, let me show you another example. Suppose you have a class Person<\/code> and you want that each person has a String name<\/code> and an int age<\/code>. You can achieve this by letting the constructor require both. For example:<\/p>\n
public class Person {\n    private final String name;\n    private final int age;\n\n    public Person(String name, int age) {\n        this.name = name;\n        this.age = age;\n    }\n\n    public String getName() { return name; }\n    public String getAge() { return age; }\n}\n<\/code><\/pre>\n
Now you can create instance of this class by calling the constructor and providing both, a name and an age:<\/p>\n
Person person = new Person(\"John\", 20);\n<\/code><\/pre>\n
But what you are trying to do is just calling it like new Person()<\/code>, without supplying any name or age, despite the constructor requiring it.<\/p>\n<\/p><\/div>\n
