Thread: Array of a Class

Hi, I'm triying to fill an array of class "Months"

All I'm triying to fill is something like this: "array[position].atribute"
Every Month must have name and days;

I get java.lang.NullPointerException , I don't understand why, I tryed using getter and setter but I don't fix it, I don't understand what's wrong, I don't get any compilation errors.

Thank you.

import java.util.Scanner;
 
public class Arrays {
	public static void main(String[] args) {
		Scanner keyboard = new Scanner(System.in);
		Months [] array = new Months[12];
 
		for(int i=0; i<array.length; i++){
			System.out.println("Introduzca el nombre del mes:\t"+(i+1));
			array[1].name = keyboard.nextLine();
			System.out.println("Introduzca los días que tiene el mes:\t");
			array[i].days = keyboard.nextInt();
		}
		keyboard.close();
		for(int i=0; i<array.length; i++){
			System.out.println(array[0].name);
			System.out.println(array[0].days);
		}
	}
}
class Months {
	String name;
	int days;
}

Exception in thread "main" java.lang.NullPointerException
at Ejercicio03.main(Ejercicio03.java:26)

The name of the class is really Ejercicio03 and there is more lines but I simplified because if i fix to add a name i will know to add more attributes tt

Sorry for my noob question, but, are you telling me that I need to instance 12 objects and full my array with these 12 objects? like this:

 
Months m = new Months();
Months[] array = new Months[12];
 
for(int i=0;i<array.length;i++)
	array[i]=m;

But how could I loop for do 12 objects with different attributes each??

Thank you very much, now I understand it better, I did this:

Meses [] array = new Meses[2];
 
for(int i=0;i<array.length;i++)
	array[i]= new Meses();

I still had problems, but the problem is now solved, I'm just blind I was filling the months fine, but all positions of array show me the First position.
If you check the code I always showing array[0] (12 times -.-)

Now works great.

Thank you again.
