Arrays Can Be Jagged

In languages like C and C++, each subarray of a multidimensional array must have the same dimensions. In Java and C# arrays do not have to be uniform because jagged arrays can be created as one-dimensional arrays of arrays. In a jagged array the contents of the array are arrays which may hold instances of a type or references to other arrays. For this reason the rows and columns in a jagged array need not have uniform length as can be seen from the following code snippet:

 int [][]myArray = new int[2][]; 
  myArray[0] = new int[3]; 
  myArray[1] = new int[9];

The above code snippet is valid for both C# and Java.
