给定一个整数进行质因数分解

package showTwos;

import java.util.Scanner;

public class ShowTwos {

//用户输入一整数，将其进行质因数分解，并打印分解结果。
    public static void main(String[] args) {
        System.out.print("input an integer: ");
        Scanner console = new Scanner(System.in);
        int number = console.nextInt();
        
        System.out.print(number + " = ");
        showTwos(number);
    }

    public static void  showTwos(int number)
    {
        int[] coefficient = new int[number];
        int count = 0;
        
       while(number != 1)
       {
           for(int i = 2;i <= number;i++)
                   
                  if(number % i == 0)
                  {
                      coefficient[count] = i;
                      count++;
                      number = number / i;
                  } 
       }
//结果类似于：18 = 2 * 3 * 3；打印过程属于篱笆桩循环问题。
       System.out.print(coefficient[0]);
        for(int i = 1;i < count ;i++)
            System.out.print(" * " + coefficient[i]);    
    }
}
