Jagged Arrays

A jagged array is an array whose elements are arrays. The elements of a jagged array can
be of different dimensions and sizes. A jagged array is sometimes called an "array-of-
arrays."

//Decalaring a Jagged Array
int[][] myJaggedArray = new int[3][];

//Initialize the elements of the Jagged Array

myJaggedArray[0] = new int[5];
myJaggedArray[1] = new int[4];
myJaggedArray[2] = new int[2];

//Fill array elements with values.

myJaggedArray[0] = new int[] {1,3,5,7,9};
myJaggedArray[1] = new int[] {0,2,4,6};
myJaggedArray[2] = new int[] {11,22};

You can access individual array elements like these examples:
// Assign 33 to the second element of the first array:
myJaggedArray[0][1] = 33;
// get the value of second element of the third array:
int i = myJaggedArray[2][1];
