Theory questions about Java

[s3a]

Thanks to both of you. But, I just have another question (which I got when read what dlorde said (or you - depending on who's reading this)): how can the length of the 2nd dimension of an array vary?

Here is an example I made for myself and no matter the integer value of the "index" variable, the length is always the same:

public class temp
{
	public static void main(String[] args)
	{
		char[][] array = new char[5][10];
		for(int index = 0; index < array.length; index++)
			int theLength = array[index].length;
		System.out.println(theLength);
	}
}
