Can I pass an array of arrays of String (String[][]) to a function in Java?

Question

I've got a constructor like this:

public Cat(String name, String[][] friendsOfFriendsNames){...}

And I would like to create a new Cat like this:

Cat cat = new Cat("Maurycy", {{"Adam", "Greta"}, {"Jurek", "Tyrmand"}});

However I am getting Syntax error on token(s), misplaced construct(s) error in Eclipse.

It turns out that I can introduce a new variable like friendsOfFriendsNames and then pass it to the constructor. Eclipse doesn't raise any error then.

String[][] friendsOfFriendsNames = {{"Adam", "Greta"}, {"Jurek", "Tyrmand"}};

Cat cat = new Cat("Maurycy", friendsOfFriendsNames);

Why is it so? Is it possible to pass {{"Adam", "Greta"}, {"Jurek", "Tyrmand"}} directly to the constructor? If so, how should I do it?

You have to tell Java what type of array it is, e.g.

Cat cat = new Cat("Maurycy", new String[][]{{"Adam", "Greta"}, {"Jurek", "Tyrmand"}});

Try like this:

new String[][]{{"Adam", "Greta"}, {"Jurek", "Tyrmand"}}
