Parsing
In your example, calling Integer.parseInt on a string is parsing this string to find an integer.

So, if you have:

String someString = "123";
And then you invoke:

int i = Integer.parseInt( someString );
You're telling java to analyze the "123" string and find an integer there.

Arrays:

String[] suit = { "Clubs", "Diamonds", "Hearts", "Spades" };
String[] rank = { "2", "3", "4", "5", "6", "7", "8", "9", "10",
                  "Jack", "Queen", "King", "Ace"
                }

 // declares an array of integers
        int[] anArray;

        // allocates memory for 10 integers
        anArray = new int[10];

2D ARRAY
double[][] a = new double[M][N];
