<identifier> expected when creating an array?

Question

I am writing an airline program that will allow the user to input names and meal choice for each seating section economy, business, and first. I am trying to save all the names and meals into an array. but I am getting a syntax error.

I get expected message when I implement my flyer array.

I have looked on stack overflow. From what I can tell it should be ok to initialize my array this way.

Thanks for any help.

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Flyers 
{    
    public Flyers()
    {

    }

    public List<String> seat = new ArrayList<>();
    int numberOfFlyers;
    int numberOfMeals;
    String name;
    String meal;    

    String[][] flyer;

    public void addEconomyFlyer()
    {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter number of economy seats sold: ");
        numberOfFlyers = in.nextInt();

        flyer = new [numberOfFlyers][numberOfFlyers];
    }  
}

What do you think new [numberOfFlyers][numberOfFlyers] does and why do you think so? — Sotirios Delimanolis

Why are you making flyer a two-dimensional array? It doesn't make much sense to me. — Dawood ibn Kareem

I want each [][] to have the same number of items that is equal to the number of people on the plane. Then I will add a nested for loop that will add a name for each of the flyers, and a meal choice. ultimately i need to be able to print out the array Name and their Meal choice. — twjohns29

OK, I think you've misunderstood what a two-dimensional array does. Suppose there are 300 people on the plane. new String[numberOfFlyers][numberOfFlyers] will create 90000 Strings. Do you think you might be better off with two one-dimensional arrays? One for the names and one for the meal choices? — Dawood ibn Kareem

Almost, the issue here is you haven't specified a type for the array.

flyer = new [numberOfFlyers][numberOfFlyers];

should probably be

flyer = new String[numberOfFlyers][numberOfFlyers];

However that doesn't make a lot sense. One solution is to use,

flyer = new String[numberOfFlyers][2];

where 0 is name and 1 is meal. But, really you should probably have a flyer POJO,

flyer = new Flyer[numberOfFlyers];

Where Flyer might look something like,

class Flyer {
  Flyer(String name, String mealType) {
    this.name = name;
    this.mealType = mealType;
  }
  String name;
  String mealType;
  public String toString() {
    return "Name: " + name + ", Meal: " + mealType;
  }
}

Then you can create new Flyer(s) and call toString() in your loop. You might also choose to add getter and setter functions for name and mealType.

change :

flyer = new [numberOfFlyers][numberOfFlyers];

to:

flyer = new String[numberOfFlyers][numberOfFlyers];

When creating any array in Java, you need to provide the data type as well with new operator.
