Stream builder() returns a builder for a Stream.
Syntax :
static <T> Stream.Builder<T> builder() where, T is the type of elements.
Return Value : A stream builder.
Example 1 :
// Java code for Stream builder() import java.util.*;
import java.util.stream.Stream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Using Stream builder()
Stream.Builder<String> builder = Stream.builder();
// Adding elements in the stream of Strings
Stream<String> stream = builder.add( "Geeks" ).build();
// Displaying the elements in the stream
stream.forEach(System.out::println);
}
} |
Output :
Geeks
Example 2 :
// Java code for Stream builder() import java.util.*;
import java.util.stream.Stream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Using Stream builder()
Stream.Builder<String> builder = Stream.builder();
// Adding elements in the stream of Strings
Stream<String> stream = builder.add( "Geeks" )
.add( "for" )
.add( "Geeks" )
.add( "GeeksQuiz" )
.build();
// Displaying the elements in the stream
stream.forEach(System.out::println);
}
} |
Output :
Geeks for Geeks GeeksQuiz
Example 3 :
// Java code for Stream builder() import java.util.*;
import java.util.stream.Stream;
import java.util.stream.Collectors;
class GFG {
// Driver code
public static void main(String[] args)
{
// Using Stream builder()
Stream.Builder<String> builder = Stream.builder();
// Adding elements in the stream of Strings
Stream<String> stream = builder.add( "GEEKS" )
.add( "for" )
.add( "Geeks" )
.add( "GeEKSQuiz" )
.build();
// Converting elements to Lower Case
// and storing them in List list
List<String> list = stream.map(String::toLowerCase)
.collect(Collectors.toList());
// Displaying the elements in list
System.out.println(list);
}
} |
Output :
[geeks, for, geeks, geeksquiz]
