Question412:

> Write a program that outputs the string representation of numbers from 1 to n.
> 
> But for multiples of three it should output “Fizz” instead of the number and for the multiples of five output “Buzz”. For numbers which are multiples of both three and five output “FizzBuzz”.
> 
> 中文解释：  
> 3的倍数输出 Fizz  
> 5的倍数输出 Buzz  
> 即是3的倍数也是5的倍数输出 FizzBuzz

Example:
     n = 15,
    
     Return:
    [
     "1",
     "2",
     "Fizz",
     "4",
     "Buzz",
     "Fizz",
     "7",
     "8",
     "Fizz",
     "Buzz",
     "11",
     "Fizz",
     "13",
     "14",
     "FizzBuzz"
    ]

很简单的遍历，然后对每个数取余获取结果，根据结果不同进行相应判断处理。  
实现代码：

package leetcode;
    
    import utils.InputUtil;
    import utils.LogUtil;
    
    import java.util.ArrayList;
    import java.util.List;
    
    public class Question412 { 
    
        public static List<String> fizzBuzz(int num) {
            List<String> result = new ArrayList<String>();
    
            for(int i=1; i<=num; i++){
                if(i%3 == 0 && i%5 != 0){
                    result.add("Fizz");
                }else if(i%3 != 0 && i%5 == 0){
                    result.add("Buzz");
                }else if(i%3 == 0 && i%5 == 0){
                    result.add("FizzBuzz");
                }else{
                    result.add(new Integer(i).toString());
                }
            }
            return result;
        }
    
        public static void main(String[] args) {
            //控制台输入数据
            int num = InputUtil.inputInt("输入整数:");
            //处理函数
            List<String> result = fizzBuzz(num);
            //打印结果
            LogUtil.printList(result);
    
        }
    }
