Java LongStream forEachOrdered()用法及代碼示例

LongStream forEachOrdered(LongConsumer action)以遇到順序對此流的每個元素執行一個動作。 LongStream forEachOrdered(LongConsumer action)是一種終端操作，即，它可以遍曆流以產生結果或副作用。

用法:

void forEachOrdered(LongConsumer action)

參數：LongConsumer表示一個接受單個long值參數且不返回結果的操作。長期以來，這是Consumer的原始類型專業化。

注意：如果流具有已定義的遇到順序，則forEachOrdered(LongConsumer action)以該流的遇到順序對此流的每個元素執行一個動作。

示例1:

// Java code for LongStream forEachOrdered 
// (LongConsumer action) in Java 8 
import java.util.*; 
import java.util.stream.LongStream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
        // Creating an LongStream 
        LongStream stream = LongStream.of(2L, 3L, 4L, 5L); 
  
        // Using LongStream.forEachOrdered 
        stream.forEachOrdered(System.out::println); 
    } 
}

輸出：

示例2:

// Java code for LongStream forEachOrdered 
// (LongConsumer action) in Java 8 
import java.util.*; 
import java.util.stream.LongStream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
        // Creating an LongStream 
        LongStream stream = LongStream.range(5L, 11L); 
  
        // Using LongStream.forEachOrdered() on 
        // sequential stream 
        stream.forEachOrdered(System.out::println); 
    } 
}

輸出：

示例3:

// Java code for LongStream forEachOrdered 
// (LongConsumer action) in Java 8 
import java.util.*; 
import java.util.stream.LongStream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
        // Creating an LongStream 
        LongStream stream = LongStream.range(5, 11); 
  
        // Using LongStream.forEachOrdered() on 
        // parallel stream 
        stream.parallel().forEachOrdered(System.out::println); 
    } 
}
