    Default Exception when creating an array

    I'm losing the will to live now.

    I have created a class that simply initializes a number an then has a function that returns it. If I run the class normally it will return the number fine but whenever I want to create an array, it returns an exception.

    This initializes the array and prints the number to the the console:

    	public Game()
    	{
    		player[] p;
    		p = new player[1];
    		System.out.print(p[0].getX());
    	}

    And the class:

    public class player
    {
    	int x, y;
    	public player()
    	{
    		x=100;
    		y=100;
    	}
    	public int getX()
    	{
    		return x;
    	}
    }

    Default Re: Exception when creating an array

    you are making a new array object. this array object holds player objects
    when you call your array and ask it for the first player object it sees that it has no players inside it, thus it can not run your get method.

    effectively:

    System.out.print(p[0].getX());

    is saying:

    System.out.print(null.getX());

    TADA!
