代码如下:

package StreamDemoFinal;public class Actor {private String name;public Actor(String name) {this.name = name;}public String getName() {return name;}public void setName(String name) {this.name = name;}
}

package StreamDemoFinal;import java.util.ArrayList;
import java.util.stream.Stream;public class StreamTest {public static void main(String[] args){ArrayList<String> manList = new ArrayList<String>();manList.add("周润发");manList.add("成龙");manList.add("刘德华");manList.add("吴京");manList.add("周星驰");manList.add("李连杰");ArrayList<String> womanList = new ArrayList<String>();womanList.add("林心如");womanList.add("张曼玉");womanList.add("林青霞");womanList.add("柳岩");womanList.add("林志玲");womanList.add("王祖贤");//男演员只要名字为3个字的前3人Stream<String> manStream = manList.stream().filter(s->s.length()==3).limit(3);Stream<String> womanStream = womanList.stream().filter(s->s.startsWith("林")).skip(1);Stream<String> stream = Stream.concat(manStream, womanStream);//        stream.map(Actor::new).forEach(System.out::println);stream.map(Actor::new).forEach(p->System.out.println(p.getName()));}
}

另外一种写法:

代码如下:

package StreamDemoFinal;import java.util.ArrayList;
import java.util.stream.Stream;public class StreamTest {public static void main(String[] args){ArrayList<String> manList = new ArrayList<String>();manList.add("周润发");manList.add("成龙");manList.add("刘德华");manList.add("吴京");manList.add("周星驰");manList.add("李连杰");ArrayList<String> womanList = new ArrayList<String>();womanList.add("林心如");womanList.add("张曼玉");womanList.add("林青霞");womanList.add("柳岩");womanList.add("林志玲");womanList.add("王祖贤");Stream.concat(manList.stream().filter(s->s.length()==3).limit(3),womanList.stream().filter(s->s.startsWith("林")).skip(1)).map(Actor::new).forEach(p->System.out.println(p.getName()));}
}
