Stream toArray() in Java with Examples
Stream toArray() returns an array containing the elements of this stream. It is a terminal operation i.e, it may traverse the stream to produce a result or a side-effect. After the terminal operation is performed, the stream pipeline is considered consumed, and can no longer be used.
Syntax :
Object[] toArray()
Return Value : The function returns an array containing the elements of this stream.
Example 1 :
import java.util.*;
import java.util.stream.Stream;
class GFG {
public static void main(String[] args)
{
Stream<Integer> stream = Stream.of( 5 , 6 , 7 , 8 , 9 , 10 );
Object[] arr = stream.toArray();
System.out.println(Arrays.toString(arr));
}
}
|
Output :
[5, 6, 7, 8, 9, 10]
Example 2 :
import java.util.*;
import java.util.stream.Stream;
class GFG {
public static void main(String[] args)
{
Stream<String> stream = Stream.of( "Geeks" , "for" ,
"Geeks" , "GeeksQuiz" );
Object[] arr = stream.toArray();
System.out.println(Arrays.toString(arr));
}
}
|
Output :
[Geeks, for, Geeks, GeeksQuiz]
Example 3 :
import java.util.*;
import java.util.stream.Stream;
class GFG {
public static void main(String[] args)
{
Stream<String> stream = Stream.of( "Geeks" , "for" ,
"gfg" , "GeeksQuiz" );
Object[] arr = stream.filter(str
-> str.startsWith( "G" ))
.toArray();
System.out.println(Arrays.toString(arr));
}
}

Output :
[Geeks, GeeksQuiz]
