Java Short reverseBytes()用法及代码示例

Short类的reverseBytes()方法是Java中的内置方法，用于返回通过反转指定的short值的二进制补码表示形式的字节顺序而获得的值。

用法:

public static short reverseBytes(short a)

参数：该方法采用一个简短类型的参数a，其字节将被反转。

返回值：该方法将返回通过反转指定的short值中的字节获得的值。

例子：

Input: 75
Output: 1258291200
Explanation:
Consider an short a = 75 
Binary Representation = 1001011
Number of one bit = 4 
After reversing the bytes = 1258291200

Input: -43
Output: -704643073

以下示例程序旨在说明Short.reverseBytes()方法：

示例1:为正数。

// Java program to illustrate the 
// Short.reverseBytes() method 
  
import java.lang.*; 
  
public class Geeks { 
  
    public static void main(String[] args) 
    { 
  
        // Create a Short instance 
        short a = 61; 
  
        // Print the value before reversal of Bytes 
        System.out.println("Original value = " + a); 
  
        // Reverse the bytes in the specified short value 
        // Using reverseBytes() method 
        System.out.println("After reversing the bytes :  \n"
                           + "New value : "
                           + Short.reverseBytes(a)); 
    } 
}

输出：

Original value = 61
After reversing the bytes :  
New value : 15616

示例2:为负数。

// Java program to illustrate the 
// Short.reverseBytes() method 
  
import java.lang.*; 
  
public class Geeks { 
  
    public static void main(String[] args) 
    { 
  
        // Create a Short instance 
        short a = -45; 
  
        // Print the value before reversal of Bytes 
        System.out.println("Original value = " + a); 
  
        // Reverse the bytes in the specified short value 
        // Using reverseBytes() method 
        System.out.println("After reversing the bytes :  \n"
                           + "New value : "
                           + Short.reverseBytes(a)); 
    } 
}

输出：

Original value = -45
After reversing the bytes :  
New value : -11265
