分解一个long整数为质数因子相乘

import java.util.*;
public class Main{
public static void main(String[]args){
Scanner s=new Scanner (System.in);
long ulDataInput=s.nextLong();
String str=getResult(ulDataInput);
System.out.println(str);
}
public static String getResult(long ulDataInput){
StringBuffer str=new StringBuffer();
int n=2;
while(n<=ulDataInput){
if(ulDataInput%n==0){
if(ulDataInput==n){
str.append(n+" ");
break;
}else{
str.append(n+" ");
ulDataInput/=n;
}
}else{
n++;
}
}
return str.toString();
}
}
