It took me about 15 minutes to implement the FizzBuzz in which most of the time spent on setting up a new java project in Eclipse. Rewritten the code did not take long.
When I started using Eclipse for the first time, I encountered a lot of minor challenges. One of the challenges was setting up the java project and adding new java class into the package.
After finishing the main class, I also had problem when adding the JUnit test case to the package. It took a while to get the right syntax for assertEquals and get the TestFuzzBuzz pass.
Since it’s been a long time from my undergrad that I’ve coded Java, I’ve also encountered a lot of syntax error and mistype the keywords. By using Eclipse, it's a lot easier to code, compile, and package Java project compare to using command prompt when I first learned Java programming 7 years ago.
Here’s my code for the FizzBuzz:
public class FizzBuzz {
public static void main(String[] args) {
for (int i=1; i<=100; i++) {
System.out.println(getFizzBuzz(i));
}
}
static String getFizzBuzz(int i) {
if ((i%3==0) && (i%5==0))
return "FuzzBuzz";
else if (i%3==0) return "Fizz";
else if (i%5==0) return "Buzz";
return Integer.toString(i);
}
}
Here's my code for the JUnit test case:
import static org.junit.Assert.assertEquals;
import org.junit.Test;
public class TestFuzzBuzz {
@Test
public void Testfuzz () {
assertEquals("1",FizzBuzz.getFizzBuzz(1));
assertEquals("Fizz",FizzBuzz.getFizzBuzz(3));
assertEquals("FuzzBuzz",FizzBuzz.getFizzBuzz(15));
assertEquals("Buzz",FizzBuzz.getFizzBuzz(5));
}
}
