题目：
Write a program that prints the numbers from 1 to 100.
But for multiples of three print "Fizz" instead of the
number and for the multiples of five print "Buzz". For
numbers which are multiples of both three and five
print "FizzBuzz".
Sample output:
1
2
Fizz
4
Buzz
Fizz
7
8
Fizz
Buzz
11
Fizz
13
14
FizzBuzz
16
17
Fizz
19
Buzz
... etc up to 100
我的编程实现如下：
public class Divisor {
public static final int ONE = 1;
public static final int TWO = 2;
public static final int THREE = 3;
public static final int FOUR = 4;
public static final int FIVE = 5;
public static final int SIVE = 6;
public static final int SEVEN = 7;
public static final int EIGHT = 8;
public static final int NINE = 9;
}
public class MyMathUtils {
//判断能否被divisor整除
public static boolean isDiviByNumber(int number, int divisor) {
if (number % divisor == 0) {
return true;
}
return false;
}
//判断同时能否被divisor1， divisor2整除
public static boolean isDiviByNumber(int number, int divisor1, int divisor2) {
Boolean result = false;
if (isDiviByNumber(number, divisor1)) {
result = isDiviByNumber(number, divisor2);
}
return result;
}
}
public class Hiker {
private static final int DIVISOR1 = Divisor.THREE;
private static final int DIVISOR2 = Divisor.FIVE;
private static final String FIZZ = "Fizz";
private static final String BUZZ = "Buzz";
private static final String FIZZBUZZ = "FizzBuzz";
public static void printNumber() {
for (int i = 1; i <= 100; i++) {
String result = getPrintResult(i, DIVISOR1, DIVISOR2);
System.out.println(result);
}
}
private static String getPrintResult(int i, int divisor1, int divisor2) {
String result = FIZZ;
if (MyMathUtils.isDiviByNumber(i, DIVISOR1, DIVISOR2)) {
result = FIZZBUZZ;
} else if (MyMathUtils.isDiviByNumber(i, DIVISOR1)) {
result = FIZZ;
} else if (MyMathUtils.isDiviByNumber(i, DIVISOR2)) {
result = BUZZ;
} else {
result = i + "";
}
return result;
}
}
public class HikerTest {
@Test
public void life_the_universe_and_everything() {
Hiker.printNumber();
}
}
不知道这样子重构是否有缺陷，希望大家评论一下，从哪方面评论都可以，谢谢！
