如下是一段 Spring 代码： Flux.range(1, 10).__(2).subscribe(x-> System.out.print(x+" ")); System.out.println(); Flux.range(1, 10).__(2).subscribe(x-> System.out.print(x+" ")); System.out.println(); Flux.range(1, 10).__(i -> i < 5).subscribe(x-> System.out.print(x+" ")); System.out.println(); Flux.range(1, 10).__(i -> i == 6).subscribe(x-> System.out.print(x+" ")); 若你想要要想输出下列结果： 1 2 9 10 1 2 3 4 1 2 3 4 5 6

可以将代码修改为以下形式：

Flux.range(1, 10).take(2).subscribe(x-> System.out.print(x+" "));
System.out.println();
Flux.range(1, 10).takeLast(2).subscribe(x-> System.out.print(x+" "));
System.out.println();
Flux.range(1, 10).takeWhile(i -> i < 5).subscribe(x-> System.out.print(x+" "));
System.out.println();
Flux.range(1, 10).filter(i -> i <= 6 && i >= 1).subscribe(x-> System.out.print(x+" "));

输出结果为：`1 2 9 10 1 2 3 4 1 2 3 4 5 6`
