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 :
// Java code for Stream toArray()import java.util.*;import java.util.stream.Stream;  class GFG {      // Driver code    public static void main(String[] args)    {        // Creating a Stream of Integers        Stream<Integer> stream = Stream.of(5, 6, 7, 8, 9, 10);          // Using Stream toArray()        Object[] arr = stream.toArray();          // Displaying the elements in array arr        System.out.println(Arrays.toString(arr));    }} |
Output :
[5, 6, 7, 8, 9, 10]
Example 2 :
// Java code for Stream toArray()import java.util.*;import java.util.stream.Stream;  class GFG {      // Driver code    public static void main(String[] args)    {        // Creating a Stream of Strings        Stream<String> stream = Stream.of("Geeks", "for",                                          "Geeks", "GeeksQuiz");          // Using Stream toArray()        Object[] arr = stream.toArray();          // Displaying the elements in array arr        System.out.println(Arrays.toString(arr));    }} |
Output :
[Geeks, for, Geeks, GeeksQuiz]
Example 3 :
// Java code for Stream toArray()import java.util.*;import java.util.stream.Stream;  class GFG {      // Driver code    public static void main(String[] args)    {        // Creating a Stream of Strings        Stream<String> stream = Stream.of("Geeks", "for",                                          "gfg", "GeeksQuiz");          // Using Stream toArray() and filtering        // the elements that starts with 'G'        Object[] arr = stream.filter(str                                     -> str.startsWith("G"))                           .toArray();          // Displaying the elements in array arr        System.out.println(Arrays.toString(arr));    }} |
Output :
[Geeks, GeeksQuiz]
