Java LongStream.Builder中的build()方法

build()LongStream.Builder类的方法生成流并返回生成的流。以下是语法:

LongStream build()

为Java中的LongStream.Builder类导入以下软件包:

import java.util.stream.LongStream;

声明一个LongStream.Builder并添加元素:

LongStream.Builder builder = LongStream.builder();

builder.add(24000L);
builder.add(47470L);
builder.add(12999L);

现在,使用该build()方法来构建流:

builder.build()

以下是显示如何build()在Java中实现LongStream.Builder方法的示例:

示例

import java.util.stream.LongStream;
public class Demo {
   public static void main(String[] args) {
      LongStream.Builder builder = LongStream.builder();
      builder.add(24000L);
      builder.add(47470L);
      builder.add(12999L);
      builder.add(55757L);
      builder.add(12999L);
      builder.add(55757L);
      builder.build().forEach(System.out::println);
   }
}

输出

24000
47470
12999
55757
12999
55757
