In this Java program, you’ll learn how to display factors of a positive or negative number. In this program, we used the following java basics such as for loop, and if..else condition.
Here is the code of the program to display factors of a positive or negative number:
//Java Program to Display Factors of a Positive Number
import java.util.Scanner;
public class JavaPrograms {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a Number: ");
int number = sc.nextInt();
System.out.print("Factors of " + number + " are: ");
// loop runs from 1 to 60
for (int i = 1; i <= number; ++i) {
// if number is divided by i
// i is the factor
if (number % i == 0) {
System.out.print(i + " ");
}
}
}
}
Enter a Number:
20
Factors of 20 are: 1 2 4 5 10 20
//Java Program to Display Factors of a Negative Number
import java.util.Scanner;
public class JavaPrograms {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a Number: ");
int number = sc.nextInt();
System.out.print("Factors of " + number + " are: ");
// run loop from -60 to 60
for (int i = number; i <= Math.abs(number); ++i) {
// skips the iteration for i = 0
if (i == 0) {
continue;
} else {
if (number % i == 0) {
System.out.print(i + " ");
}
}
}
}
}
Enter a Number:
-20
Factors of -20 are: -20 -10 -5 -4 -2 -1 1 2 4 5 10 20
