Java 大家一起看看继承创建的适配器类。

public interface Generator<T> {T next();}//生成器

public class Fibonacci implements Generator<Integer>{private int count = 0;private int fib(int n){if(n<2) return 1;return fib(n-1) + fib(n-2);}public Integer next() {System.out.println("count:"+count);return fib(count++);}public static void main(String[] args){Fibonacci gen = new Fibonacci();for(int i=0;i<18;i++){System.out.println(gen.next()+ " ");}}}

public class IterableFib extends Fibonacci implements Iterable<Integer>{private int n;public IterableFib(int count){ n=count ; }public Iterator<Integer> iterator() {return new Iterator<Integer>(){public boolean hasNext(){ return n>0 ;}public Integer next(){n--;System.out.println("n:"+n);return IterableFib.this.next();}public void remove(){}};} public static void main(String[] args){IterableFib ife = new IterableFib(18); for(int i:ife)System.out.println(i + " ");//猜得到输出结果吗}}///整个适配器类的用法有何见解
