The build() method in Java Stream.Builder

The build() method in Stream.Builder class is used to build the stream. It returns the built stream.

The syntax is as follows:

Stream<T>l build()

Import the following package for the Stream.Builder class in Java:

import java.util.stream.Stream;

Declare a Stream.Builder:

Stream.Builder<String> builder = Stream.builder();

Add some elements in the stream:

builder.add("One");
builder.add("Two");
builder.add("Three");

Now, use the build() method:

Stream<String> str = builder.build();

The following is an example displaying how to implement build() method of Stream.Builder in Java:
