How do you How do you write the special number program in java?

Answer 1

// Addition program that displays the sum of two numbers.

import java.util.Scanner; // program uses class Scanner

public class Addition

{

// main method begins execution of Java application

public static void main( String args[] )

{

// create Scanner to obtain input from command window

Scanner input = new Scanner( System.in );

int number1; // first number to add

int number2; // second number to add

int sum; // sum of number1 and number2

System.out.print( "Enter first integer: " ); // prompt

number1 = input.nextInt(); // read first number from user

System.out.print( "Enter second integer: " ); // prompt

number2 = input.nextInt(); // read second number from user

sum = number1 + number2; // add numbers

System.out.printf( "Sum is %d\n", sum ); // display sum

} // end method main

} // end class Addition

Answer 2

//Program to check whether the given no is special or not

import java.io.*;

Public class special

{

Public static void main(String arg[]) throws IO Exception

{

InputstreamReader read=new Input Stream Reader(system.in)

BufferReader input=new BufferReader(rtead0:

System.out.println("Entrer the special no")

String X=input.read Line();

int n=Integer.parseInt(x):

int sum=0,f=1,d=0,num=n;

for(;n>o;)//(n!=0)

{

d=n%10;

for(int i=1;i<=d;i++)

{

f=f*i

}

sum=sum+f;

f=1;

n=n/10;

}

if(sum==num)

System.out.println("It is a special no")

else

System.out.println("It is not a special no");

}

}

Answer 3

In Java applications, use the Scanner class. For instance:

import java.util.scanner;

...

Scanner input = new Scanner(System.in);

System.out.println("Type a word: ");

String word = input.nextLine();

Oh, and by the way, the Scanner class didn't exist until jdk 1.5.
