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 s t
