IntStream boxed()返回一個包含此流元素的流,每個元素都裝在整數中。
注意:IntStream boxed()是中間操作。這些操作總是很懶。在Stream實例上調用中間操作,並在完成處理後將中間實例作為輸出提供。
用法:
Stream<Integer> boxed()
參數:
- Stream : 支持順序和並行聚合操作的一係列元素。
- Integer : Integer類將原始類型int的值包裝在對象中。類型為Integer的對象包含一個類型為int的字段。
返回值:該函數將裝箱的流返回到整數。
示例1:
// Java code for IntStream boxed()
import java.util.*;
import java.util.stream.Stream;
import java.util.stream.IntStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an IntStream
IntStream stream = IntStream.range(3, 8);
// Creating a Stream of Integers
// Using IntStream boxed() to return
// a Stream consisting of the elements
// of this stream, each boxed to an Integer.
Stream<Integer> stream1 = stream.boxed();
// Displaying the elements
stream1.forEach(System.out::println);
}
}
輸出:
3 4 5 6 7
示例2:
// Java code for IntStream boxed()
import java.util.*;
import java.util.stream.Stream;
import java.util.stream.IntStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an IntStream
IntStream stream = IntStream.range(3, 8);
// Creating a Stream of Integers
// Using IntStream boxed() to return
// a Stream consisting of the elements
// of this stream, each boxed to an Integer.
Stream<Integer> stream1 = stream.boxed();
Stream<Object> stream2 = Stream.concat(stream1,
Stream.of("Geeks", "for", "Geeks"));
// Displaying the elements
stream2.forEach(System.out::println);
}
}
輸出:
3 4 5 6 7 Geeks for Geeks
