 arrays 

 
	arrays (or lists or tables) are a way
	to handle bigger amounts of data. an array
	containing instances of a certain class is
	defined by Name_of_The_Class[]


	examples of syntax:

	// a String array called string_array
	String[]	string_array;

	// reserve room for three instances of String class
	string_array	= new String[3];

	// the three places are now empty, let's fill them
	string_array[0]	= "first";
	string_array[1]	= "second";
	string_array[2]	= "third";

	// lets define another array and set the value at the same time
	String[] string_array2 = {"hii", "hoo", "haa", "huu"};

	// lets define an integer array
	int[] integerlist = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11};

	// to go through all the values in the array, you can
	// use array.length

	// the indexes inside arrays start from 0! 
	// so the list that contains three instances
	// has values array[0], array[1], array[2])

	// print all the Strings in a string array
	for ( int i = 0  ;  i < string_array.length  ;  i++)
	{
		System.out.println(string_array[i]);
	}
