Question

Write a method named numberOfFactor that is able to accept a positive integer number as an argument and return the number of factors for that number. For example, 36 has 9 factors which include 1, 2, 3, 4, 6, 9, 12, 18, 36. So when  numberOfFactor(36) is called, 9 is returned.

The declaration of the method is

static int numberOfFactors(int number)

Answer 1

import java.util.*;
public class MyClass {
public static void main(String args[]) {
Scanner in=new Scanner(System.in);
System.out.println("Enter number: ");
int n=in.nextInt();
System.out.println("factor is: "+numberOfFactors(n));
}

public static int numberOfFactors(int number)
{
int cnt=0;
for(int i=1;i<=number;i++)
{
if(number%i==0)
cnt++;
}
return cnt;
}
}
