Basic concept of Double Dimensional Array

Double Dimensional arrays is consists of two subscripts : one for the row and other for the column. 

The first subscript is always the row subscript and second is column subscript.   

class  Array2D

{

    public static void main(String args[])

    { 

        int[][] A = new int[2][3] ;

        A[0][1] = 11 ;

        A[0][1] = 22 ;

        A[0][2] = 33 ;

        A[1][0] = 44 ;

        A[1][1] = 55 ;

        A[1][2] = 66 ;           

        System.out.println(" The value is " + A[0][2]) ;

        System.out.println(" The value is " + A[1][1]) ;

    }

}

Basic concept of Array in Java Program Part 1

 An Array is a group of like-typed variables that are referenced by a common name. 

                                                      OR

 An Array is the collection of Homogeneous or Similar data-type. 

Example 1

                                  // Use of integer in array 

class Array

{

    public static void main(String args[])

    {

        int[] A = new int[5] ;

        A[0] = 7 ;

        A[1] = 2 ;

        A[2] = 3 ;

        A[3] = 1 ;

        A[4] = 5 ;   

        System.out.println(" The value is " + A[2]) ;

        System.out.println(" The value is " + A[4]) ;

    }

}

=====================================================

Example 2

                                                // Addition in Array

class Array

{

    public static void main(String args[])

    {

        int[] A = new int[5] ;

        A[0] = 7 ;

        A[1] = 2 ;

        A[2] = 3 ;

        A[3] = 1 ;

        A[4] = 5 ;   

        int x = A[1] + A[4] ;        

        System.out.println(" The value is " + x) ;      

    }

}

====================================================

Example 3

                                       // Use of String in array 

class Array

{

    public static void main(String args[])

    {

        String d[] = {"Mon" , "Tue" , "Wed" , "Thurs" , "Fri" , "Sat"} ;       

        System.out.println(d[0]) ;

        System.out.println(d[2]) ;

    }

}

Algorithm and Flowchart

Algorithm

Algorithm is the step by step instructions written in simple language to perform a particular task .

Example : Write an algorithm to find the addition of Two number 

                 

Answer  :    Step 1 : Start 

                   Step 2 : Take N1 , N2 

                   Step 3 : sum = N1 + N2 

                   Step 4 : Print sum 

                   Step 5 : Stop 

Flowchart

Flowchart is a step by step process of representing the solution of a particular problem in a graphical or pictorial form.

Neon number in Java

Neon number is a number where the sum of digits of square of the number is equal to that number.

                   Example :  n=9  , p = 9 * 9 = 81   , s = 8+1 = 9   (n = s , it is neon number)

import java.util.*;

class  Neon

{

    public static void main(String[] args)

    {

        int  rem ;   int  s = 0;

        Scanner sk = new Scanner(System.in);

        System.out.print("Enter number: ");

        int n = sk.nextInt();

         

        int p = n * n ;

    

        while (p != 0)

        {

            rem = p % 10;

            s = s + rem;

            p = p / 10;

        }

        if (n == s)

        {

            System.out.println(" Neon number ");

        }

        else

        {
