Question

Write an application that displays the factorial for every integer value from 1 to 10. A factorial of a number is the product of that number multiplied by each positive integer lower than it. For example, 4 factorial is 4 * 3 * 2 * 1, or 24. Save the file as Factorials.java

Answer 1

// Factorials.java

// library

import java.util.*;

// class definition

class Factorials

{

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

try{

// variable to store Factorial

int fact=1;

// find Factorial of all from 1 to 10

for(int i=1;i<=10;i++)

{

// calculate Factorial

fact=fact*i;

// print Factorial

System.out.println("Factorial of "+i+" is: "+fact);

}

}catch(Exception ex){

return;}

}

}

Step-by-step explanation:

Declare and initialize a variable "fact=1" to store the Factorial of a number. Run a for loop from 1 to 10.Fact will multiplied by value of i and that will be the Factorial of "i".Print the Factorial of "i".This will continue for i=1 to i=10.

Output:

Factorial of 1 is: 1

Factorial of 2 is: 2

Factorial of 3 is: 6

Factorial of 4 is: 24

Factorial of 5 is: 120

Factorial of 6 is: 720

Factorial of 7 is: 5040

Factorial of 8 is: 40320

Factorial of 9 is: 362880

Factorial of 10 is: 3628800
