Jagged array is array of arrays such that member arrays can be of different sizes, i.e., we can create a 2-D arrays but with variable number of columns in each row. These type of arrays are also known as Jagged arrays. Following are Java programs to demonstrate the above concept. // Program to demonstrate 2-D jagged array in Java class Main {     public static void main(String[] args)     {         // Declaring 2-D array with 2 rows         int arr[][] = new int[2][];           // Making the above array Jagged           // First row has 3 columns         arr[0] = new int[3];           // Second row has 2 columns         arr[1] = new int[2];           // Initializing array         int count = 0;         for (int i=0; i<arr.length; i++)             for(int j=0; j<arr[i].length; j++)                 arr[i][j] = count++;           // Displaying the values of 2D Jagged array         System.out.println("Contents of 2D Jagged Array");         for (int i=0; i<arr.length; i++)         {             for (int j=0; j<arr[i].length; j++)                 System.out.print(arr[i][j] + " ");             System.out.println();         }     }
