Jagged array is a array of arrays such that member arrays can be of different sizes. In other words, the length of each array index can differ. The elements of Jagged Array are reference types and initialized to null by default. Jagged Array can also be mixed with multidimensional arrays. Here, the number of rows will be fixed at the declaration time, but you can vary the number of columns.

In Jagged arrays, user has to provide the number of rows only. If the user is also going to provide the number of columns, then this array will be no more Jagged Array.

Syntax:

data_type[][] name_of_array = new data_type[rows][]

Example:

int[][] jagged_arr = new int[4][]

 

Example 2:

 When the array size is not needed then its elements can be initialized with direct values as follows:

jagged_arr[0] = new int[] {1, 2, 3, 4};
jagged_arr[1] = new int[] {11, 34, 67};
jagged_arr[2] = new int[] {89, 23};
jagged_arr[3] = new int[] {0, 45, 78, 53, 99};
