Java 中的 IntStream rangeClosed()

原文:https://www.geeksforgeeks.org/intstream-rangeclosed-java/

IntStream range closed(int startInclusive，int endInclusive) 返回从 startInclusive(包含)到 endInclusive(包含)的 int stream，增量步长为 1。

语法:

static IntStream rangeClosed(int startInclusive,   int endInclusive)

参数:

  1. intstream: A series of original int value elements.
  2. 开始包含:包含初始值。
  3. 结束时间:包含上限。

返回值:int 元素范围的连续 IntStream。

例:

// Implementation of IntStream rangeClosed
// (int startInclusive, int endInclusive)
import java.util.*;
import java.util.stream.IntStream;

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating an IntStream
        IntStream stream = IntStream.rangeClosed(-4, 3);

        // Displaying the elements in range
        // including the lower and upper bound
        stream.forEach(System.out::println);
    }
}

输出:

-4
-3
-2
-1
0
1
2
3

注意:int stream range closed(int startInclusive，int endInclusive)基本上像 for 循环一样工作。递增值的等价序列可以按如下顺序产生:

for (int i = startInclusive; i <= endInclusive ; i++) 
{
 ...
 ...
 ...
}
