Hi

This is an exercise in NSArray Literals - you can type it in a couple of different ways to get the same result

Type1 NSArray *array name = [[NSArray alloc] initWithObjects:@"array name 1",@"array name 2",......,nil];

Type2 NSArray *array name = [NSArray arrayWithObjects:@"array name 1",@"array name 2",......,nil];

I believe there may even be a shorter way of doing it but can't remember off the top of my head

I have the same question, I thought I did right but dont know why what's wrong here. Can somebody please help me?

           self.booksArray = [NSArray arrayWithObjects:
                    @"Hamlet",
                    @"King Lear",
                    @"Othello",
                    @"Macbeth",
                    nil];
            ```

Hello, it should be in a form like this.. i'm not sure about objective C as i'm more familiar with Java but it should be similar. So its telling you to make an array called booksArray and its values are that of a string so first lets declare the array and what datatype it holds.

Form:

arraytype[] arrayname;

substitute the values:

String[] booksArray;

lastly set the book titles as a string to the array which should end up looking like this:

Form:

 arraytype[] arrayname = {string,string,string,string};

again substitute the values;

String[] booksArray = {"Hamlet", "King Lear", "Othello", "Macbeth"};

and that wraps it up i hope that helps.
