Java Character.isMirrored()方法

Character.isMirrored(int codePoint) 是java中的一个内置方法，它根据Unicode规范确定指定的字符（Unicode码位）是否是镜像的。镜像字符在从右到左的文本中显示时，其字形应该是水平镜像的。例如，’\u0028′ LEFT PARENTHESIS在语义上被定义为一个开口括号。这在从左到右的文本中会显示为”(“，但在从右到左的文本中则显示为”)”。

语法

public static boolean isMirrored(int codePoint)

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

返回值： 如果该字符是镜像的，该方法返回true；如果该字符不是镜像的或未定义，则返回false。

下面的程序说明了Character.isMirrored()方法。

程序1 :

// 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

程序2

// 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
