Java中的字符.isMirrored() 方法

字符.isMirrored(int codePoint)是Java中的一个内置方法，根据Unicode规范判断指定字符（Unicode代码点）是否被镜像。在从右到左的文本中显示时，镜像字符应使其字形水平镜像。例如，'\u0028' 左括号在语义上被定义为左括号。这将在从左到右的文本中显示为“（”，但在从右到左的文本中显示为“）”。

句法：

public static boolean isMirrored(int codePoint)

参数：整数类型的参数codePoint是要测试的字符（Unicode码点）。

返回值：如果字符被镜像，则此方法返回true，如果字符未镜像或未定义，则返回false。

下面的程序说明了字符.isMirrored() 方法：

方案一：

// Code to illustrate the isMirrored() method
import java.lang.*;
public class gfg {
  
    public static void main(String[] args)
    {
  
        // Creating 2 int primitives char1, char2
        int char1 = 0x0c05, char2 = 0x013c;
  
        // Checks if character is mirrored or not and prints
        boolean bool1 = Character.isMirrored(char1);
        String str1 = "char1 represents a mirrored character is " + bool1;
        System.out.println(str1);
  
        boolean bool2 = Character.isMirrored(char2);
        String str2 = "char2 represents a mirrored character is " + bool2;
        System.out.println(str2);
    }
}

输出：

char1 represents a mirrored character is false
char2 represents a mirrored character is false

方案二：

// Code to illustrate the isMirrored() method
import java.lang.*;
  
public class gfg {
  
    public static void main(String[] args)
    {
  
        // Create 2 int primitives c1, c2
        int c1 = 0x0c07, c2 = 0x063c;
  
        // Checks if character is mirrored or not and prints
        boolean bool1 = Character.isMirrored(c1);
        String str1 = "c1 represents a mirrored character is " + bool1;
        System.out.println(str1);
  
        boolean bool2 = Character.isMirrored(c2);
        String str2 = "c2 represents a mirrored character is " + bool2;
        System.out.println(str2);
    }
}

输出：

c1 represents a mirrored character is false
c2 represents a mirrored character is false
