IntStream boxed()返回一个包含此流元素的流，每个元素都装在整数中。

注意：IntStream boxed()是中间操作。这些操作总是很懒。在Stream实例上调用中间操作，并在完成处理后将中间实例作为输出提供。

用法:

Stream boxed()

参数：

Integer :Integer类将原始类型int的值包装在对象中。类型为Integer的对象包含一个类型为int的字段。

返回值：该函数将装箱的流返回到整数。

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 stream1 = stream.boxed();

// Displaying the elements

stream1.forEach(System.out::println);

}

}

输出：

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 stream1 = stream.boxed();

Stream stream2 = Stream.concat(stream1,

Stream.of("Geeks", "for", "Geeks"));

// Displaying the elements

stream2.forEach(System.out::println);

}

}

输出：
