Suppose you have four 500 MB hard drives plus one 2 GB flash drive. How many GB of capacity is this overall?
Sidana [21]

You would have a total of 2.5 GB of capacity.

A gigabyte consists of 1000 megabytes, so 500 megabytes make half of a gigabyte, or 0.5 gigabytes.

So 2GB + 0.5GB = 2.5GB

Write a function called factor that determines for a pair of integers whether the second integer is a factor of the first. The f
Aleks04 [339]
<h2>Answer:</h2>

//import the Scanner class to allow for user's input

import java.util.Scanner;

//Declare the class and call it FactorClass

public class FactorClass {

   

   //Declare the function factor

   //It returns either true or false, therefore the return type is boolean

   //It receives two arguments - a and b

   public static boolean factor(int a, int b){

       

       //Check if a is divisible by b.

       //Return true if yes

       if(a % b == 0){

           return true;

       }

       

       //return false if a is not divisible by b

       return false;

   

   }  // End of method factor

   

   

   //The main method to test the function factor()

   public static void main(String[] args) {

       

       //Create an object of the Scanner class

       Scanner input = new Scanner(System.in);

       

       //Prompt the user to enter the pair of numbers

       System.out.println("Enter the pair of numbers (separated by a space)");

       

       //grab and store the first number in a variable

       int firstnum = input.nextInt();

       

       //grab and store the second number in another variable

       int secondnum = input.nextInt();

       

       

       //With the variables, call the factor() method

       //If it returns true, print the adequate message

       if(factor(firstnum, secondnum)){

           System.out.println(secondnum + " is a factor of " + firstnum);

       }

       

       //If it returns false, print the adequate message

       else{

           System.out.println(secondnum + " is NOT a factor of " + firstnum);

       }

   

 }            // End of main method

   

}    // End of class declaration

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

<h2>Sample Output 1:</h2>

>> Enter the pair of numbers  separated by a space

8 4

>> 4 is a factor of 8

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

<h2>Sample Output 2:</h2>

>> Enter the pair of numbers  separated by a space

9 4

>> 4 is NOT a factor of 9

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

<h2>Explanation:</h2>

The above code has been written in Java and it contains comments explaining every segment of the code. Kindly go through the comments for better understanding of the code.

For simplicity, the code is re-written as follows with little or no comments;

import java.util.Scanner;

//Declare the class and call it FactorClass

public class FactorClass {

   

   public static boolean factor(int a, int b) {

       if(a % b == 0){

           return true;

       }

       

       //return false if a is not divisible by b

       return false;

   

   }  // End of method factor

   

   

   //The main method to test the function factor()

   public static void main(String[] args) {

       

       //Create an object of the Scanner class

       Scanner input = new Scanner(System.in);

       

       //Prompt the user to enter the pair of numbers

       System.out.println("Enter the pair of numbers (separated by a space)");

       

       //grab and store the first number in a variable

       int firstnum = input.nextInt();

       

       //grab and store the second number in another variable

       int secondnum = input.nextInt();

       

       

       if(factor(firstnum, secondnum)){

           System.out.println(secondnum + " is a factor of " + firstnum);

       }

       

       else{

           System.out.println(secondnum + " is NOT a factor of " + firstnum);

       }

    }

   

}

In what kind of attack can attackers make use of millions of computers under their control in an attack against a single server
rjkz [21]
