Java 中的 DoubleBuffer order()方法，示例

原文:https://www . geesforgeks . org/double buffer-order-methods-in-Java-with-examples/

Java . nio . DoubleBuffer类的 order() 方法用于获取这个 double buffer 实例的 ByteOrder。

语法:

public abstract ByteOrder order()

返回值:这个方法返回这个缓冲区的字节顺序。 以下是举例说明 order()方法: 例 1:

Java 语言(一种计算机语言，尤用于创建网站)

// Java program to demonstrate
// order() method

import java.nio.*;
import java.util.*;

public class GFG {

    public static void main(String[] args)
    {
        // creating object of DoubleBuffer
        // and allocating size capacity
        DoubleBuffer db
            = DoubleBuffer.allocate(4);

        // put the double value
        // in the Doublebuffer
        db.put(10.5)
            .put(20.5)
            .put(30.5)
            .put(40.5);

        // rewind the Doublebuffer
        db.rewind();

        // Retrieve the ByteOrder
        // using order() method
        ByteOrder order = db.order();

        // print the double buffer and order
        System.out.println("DoubleBuffer is : "
                           + Arrays.toString(
                                 db.array())
                           + "\nOrder: "
                           + order);
    }
}

Output: 

DoubleBuffer is : [10.5, 20.5, 30.5, 40.5]
Order: LITTLE_ENDIAN
