Syntax error Stream.Builder build() in Java

Stream.Builder build() in Java

The build() method of the Stream.Builder class builds the stream, transitioning this builder to the built state. The syntax is as follows −

Stream<T> build()

Following is an example to implement the build() method of the Stream.Builder class −

Example

import java.util.stream.Stream;
public class Demo {
   public static void main(String[] args) {
      Stream.Builder<String> builder = Stream.builder();
      builder.add("Production");
      builder.add("Marketing");
      builder.add("Finance");
      builder.add("Sales");
      builder.add("Operations");
      Stream<String> stream = builder.build();
      stream.forEach(System.out::println);
   }
}

Output

Production
Marketing
Finance
Sales
Operations

Example

Let us see another example of build() method wherein we are adding elements to the stream using the accept() method −

import java.util.stream.Stream;
public class Demo {
   public static void main(String[] args) {
      Stream.Builder<String> builder = Stream.builder();
      builder.accept("k");
      builder.accept("l");
      builder.accept("m");
      builder.accept("n");
      builder.accept("o");
      builder.accept("p");
      builder.accept("q");
      builder.accept("r");
      builder.accept("s");
      builder.accept("t");
      Stream<String> stream = builder.build();
      stream.forEach(System.out::println);
   }
}

Output

K
l
m
n
o
p
q
r
