...和foreach

public class exercise1 {public static void test(int a,String...books){for(String tmp:books){System.out.println(tmp);}System.out.println(a);}public static void main(String[] args){test(5,"11111","22222");}}

for(int i=0;i<books.length;i++) {

    String tmp = books[i];

}

=

for(String tmp:books)

<pre name="code" class="java">public static void test(int a,String...books)

形参长度可变的方法，最后一个形参类型增加...
