v Define Jagged Arrays

The other type of multidimensional array is the jagged array. A two dimensional jagged array can be thought of as a table where each row can have a different number of columns. Take for example a table where families are the rows and family members are the columns. Unless each family has the same number of members each row will have a variable number of columns. You can use a jagged array to represent such a table.

a collection of discrete no of elements in each and every row is called as jagged arrays.

1)these jagged arrays doesnt contain columns

2)a jagged array also called as dynamic array

3)jagged array is a collection of dynamic arrays

4)these are faster and also save the memory.

syntax of jagged array:

int[][]x new int [rows][]

here x is array name

Jagged Arrays

Another type of multidimensional array Jagged Array is an array of arrays in which the length of each array can differ. Example where this array can be used is to create a table in which the number of columns differ in each row. Say if row1 has 3 columns row2 has 3 columns then row3 can have 4 columns row4 can have 5 columns and so on. The following code demonstrates jagged arrays.
