/* * lesson 7 coding activity question 1 * * input a positive three digit integer. print out the digits one per line. * * sample run: enter a three digit number: 678 here are the digits: 6 7 8 */ import java. util. scanner; import java. lang. math; class lesson_7_activity_one { public static void main(string[] args) { /* write your code here * copy and paste your entire code to code runner to complete the activity, * from the first import statement to the last bracket. */ scanner scan = new scanner (system. in); system. out. println(" enter a three digit number: "); int num= scan. nextint(); int first = num % 10; int second = ( num - first ) % 100 / 10; int third = ( num - first - second ) % 1000 / 100; system. out. println("here are the digits: "); system. out. println(first); system. out. println(second); system. out. println(third); } }

The program illustrates the use of arithmetic operation; most especially, the modulo operation.

A modulo operator (represented as %) returns the remainder after two integers are divided

Take for instance:

The result is 2, because when 5 is divided by 3, the remainder is 2

The modified program in java, where comments are used to explain each line is as follows:

import java.util.Scanner;

import java.lang.Math;

class Lesson_7_Activity_One {

public static void main(String[] args) {

//This creates a scanner object

   Scanner scan = new Scanner (System.in);

//This prompts the user for a three-digit number

   System.out.println("Please enter a three-digit number:");

//This gets the input from the user

   int num= scan.nextInt();

//This calculates the first digit using the modulo operator

   int first = (num - num % 100)/100;

//This calculates the remainder

  num -= first * 100;

//This calculates the second digit using the modulo operator

   int second = (num - num % 10)/10;

//This calculates the third digit

   int third = num -second * 10;

//This prints the output header

   System.out.println("Here are the digits: ");

//This prints the first digit

   System.out.println(first);

//This prints the second digit

   System.out.println(second);

//This prints the third digit

   System.out.println(third);

}

}

At the end of the program, the first, second and third digit of the number are printed.

In stead of going number arithmetic, you could also approach it as string handling. Replace the last lines of your code (right after the scan statement) with:

String s = Integer.toString(num);

System.out.println("Here are the digits: ");

System.out.println(s.charAt(0)+"\n"+s.charAt(1)+"\n"+s.charAt(2));

your game would probably crash if its too much lag but other players will also ! xd

hope this ! xd

also, can i get brainliest ?
