Java中的字符.reverseBytes() 和示例

Java.lang。 字符.reverseBytes()是Java中的内置方法,它返回通过反转指定char值中的字节顺序获得的值。

句法:

public static char reverseBytes(char ch)

参数:该函数接受一个强制参数ch ,它表示要颠倒字节顺序的字符。

返回:此方法返回通过反转(或等效地交换)指定 char 值中的字节获得的值。

下面的程序说明了Java.lang。字符.reverseBytes()函数:
方案一:

// Java program to demonstrate the
// Character.reverseBytes() when a
  
import java.lang.*;
  
public class gfg {
  
    public static void main(String[] args)
    {
  
        // char whose byte order is to be reversed
        char c1 = '\u4d00';
        char c2 = Character.reverseBytes(c1);
  
        // prints the reversed bytes
        System.out.println("Reversing bytes on " + c1 + " gives " + c2);
    }
}
输出:
Reversing bytes on ? gives M

方案二:

// Java program to demonstrate the
// Character.reverseBytes() when a
// number is passed
  
import java.lang.*;
  
public class gfg {
  
    public static void main(String[] args)
    {
  
        // char whose byte order is to be reversed
        char c1 = '9';
        char c2 = Character.reverseBytes(c1);
  
        // prints the reversed bytes
        System.out.println("Reversing bytes on " + c1 + " gives " + c2);
  
        c1 = '7';
        c2 = Character.reverseBytes(c1);
  
        // prints the reversed bytes
        System.out.println("Reversing bytes on " + c1 + " gives " + c2);
    }
}
输出:
Reversing bytes on 9 gives ?
Reversing bytes on 7 gives ?
