Write a function called factor that determines for a pair of integers whether the second integer is a factor of the first. The function should take two integer arguments and return true if the second is a factor of the first, false otherwise. Use this function in a program that inputs a series of pairs of integers. Hint: You will want to use modulus. Output: Enter in two integers: 8 4 4 is a factor of 8 Enter in two integers 9 4 4 is NOT a factor of 9

//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

Sample Output 1:

>> Enter the pair of numbers separated by a space

8 4

>> 4 is a factor of 8

Sample Output 2:

>> Enter the pair of numbers separated by a space

9 4

>> 4 is NOT a factor of 9

Explanation:

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);

}

Formatting rows and columns is similar to cell formatting. in an openoffice calc spreadsheet, you can format data entered into rows and columns with the of the rows and columns options. you can insert rows and columns into, or delete rows and columns from, a spreadsheet. use the insert or delete rows and columns option on the insert tab. alternatively, select the row or column where you want new rows or columns to appear, right-click, and select insert only row or only column options. you can hide or show rows and columns in a spreadsheet. use the hide or show option on the format tab. for example, to hide a row, first select the row, then choose the insert tab, then select the row option, and then select hide. alternatively, you can select the row or columns, right-click, and select the hide or show option. you can adjust the height of rows and width of columns. select row and then select the height option on the format tab. similarly, select column, then select the width option on the format tab. alternatively, you can hold the mouse on the row and column divider, and drag the double arrow to the position. you can also use the autofit option on the table tab to resize rows and columns.
