Java 中的短反转字节()，示例
原文:https://www . geesforgeks . org/short-reverse bytes-in-Java-with-examples/
Short类的 reverseBytes() 方法是 Java 中的内置方法，用于返回通过反转指定短值的二进制补码表示中的字节顺序而获得的值。
语法:
public static short reverseBytes(*short a*)
参数:该方法取一个短类型的参数 a ，其字节将被反转。
返回值:该方法将返回通过反转指定短值中的字节获得的值。
示例:
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
下面的程序说明了 Short.reverseBytes()方法:
程序 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));
}
}
Output:
Original value = 61
After reversing the bytes :
New value : 15616
程序 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));
}
}
Output:
Original value = -45
After reversing the bytes :
New value : -11265
