JavaでStream APIを使ってFizzBuzzする（インデックス表示あり）

FizzBuzzWriter.java

package fizzbuzz;
 
import java.util.stream.Stream;

public class FizzBuzzWriter {
	public static void main(String[] args) {
 		// FizzBuzzの無限リスト
		Stream<FizzBuzz> fizzbuzz = Stream.iterate(new FizzBuzz(0), fb -> {
			fb.setIndex(fb.getIndex() + 1);
			return fb;
		}).map(fb -> {
			fb.setWord(
				(fb.getIndex() % 15 == 0) ? "Fizbuzz" :
				(fb.getIndex() % 3 == 0) ? "Fizz" :
				(fb.getIndex() % 5 == 0) ? "Buzz" :
				Integer.toString(fb.getIndex()));
			return fb;
		});
		
		// skipが起点、limitが表示数に対応する
		fizzbuzz.skip(1).limit(100).forEach(fb ->
			System.out.printf("%d:%s%s",
					fb.getIndex(),
					fb.getWord(),
					System.lineSeparator()));
		
	}
 
	static class FizzBuzz {
		private int index;
		private String word;
 
		public FizzBuzz(int index) {
			this.index = index;
		}
 
		public int getIndex() {
			return index;
		}
 
		public void setIndex(int index) {
			this.index = index;
		}
 
		public String getWord() {
			return word;
		}
 
		public void setWord(String word) {
			this.word = word;
		}
	}
