【画像】javaでプログラム組んでみたんだけど、どうかな？

良い子は真似しちゃダメな書き方だよ
Javaのバージョンは12ね

public static void main(String[] args) {
var fortune = Arrays.asList(new java.util.Random().nextInt(512) + 1);
fortune.stream().filter(a -> a >= 1 && a < 2)
.forEach(a -> System.out.println(“1等賞”));
fortune.stream().filter(a -> a >= 2 && a < 4)
.forEach(a -> System.out.println(“2等賞”));
fortune.stream().filter(a -> a >= 4 && a < 8)
.forEach(a -> System.out.println(“3等賞”));
fortune.stream().filter(a -> a >= 8 && a < 16)
.forEach(a -> System.out.println(“4等賞”));
fortune.stream().filter(a -> a >= 16 && a < 32)
.forEach(a -> System.out.println(“5等賞”));
fortune.stream().filter(a -> a >= 32 && a < 64)
.forEach(a -> System.out.println(“6等賞”));
fortune.stream().filter(a -> a >= 64 && a < 128)
.forEach(a -> System.out.println(“7等賞”));
fortune.stream().filter(a -> a >= 128 && a < 256)
.forEach(a -> System.out.println(“8等賞”));
fortune.stream().filter(a -> a >= 256 && a < 512)
.forEach(a -> System.out.println(“残念賞”));

}
