Java Stream.Builder中的build()方法
build()
Stream.Builder类中的方法用于构建流。它返回构建的流。
语法如下:
Stream<T>l build()
为Java中的Stream.Builder类导入以下包:
import java.util.stream.Stream;
声明一个Stream.Builder:
Stream.Builder<String> builder = Stream.builder();
在流中添加一些元素:
builder.add("One"); builder.add("Two"); builder.add("Three");
现在,使用build()
方法:
Stream<String> str = builder.build();
以下是显示如何build()
在Java中实现Stream.Builder方法的示例:
示例
import java.util.stream.Stream; public class Demo { public static void main(String[] args) { Stream.Builder<String> builder = Stream.builder(); builder.add("One"); builder.add("Two"); builder.add("Three"); builder.add("Four"); builder.add("Five"); builder.add("Six"); builder.add("Seven"); builder.add("Eight"); Stream<String> str = builder.build(); str.forEach(System.out::println); } }
输出结果
One Two Three Four Five Six Seven Eigh
