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 * 9；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]);	
	}
}
