Java Character.isMirrored()用法及代碼示例

Character.isMirrored(int codePoint)是Java中的一個內置方法，該方法確定是否根據Unicode規範對指定字符(Unicode代碼點)進行鏡像。當以從右到左的文本顯示時，鏡像字符的字形應水平鏡像。例如，“ \ u0028”左括號在語義上被定義為左括號。這將在從左到右的文本中顯示為“(”，但在從右到左的文本中顯示為“)”。

用法:

public static boolean isMirrored(int codePoint)

參數：整數類型的參數codePoint是要測試的字符(Unicode代碼點)。

返回值：如果字符已鏡像，則此方法返回true；如果字符未鏡像或未定義，則返回false。

以下示例程序旨在說明Character.isMirrored()方法：

示例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); 
    } 
}

輸出：

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

示例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); 
    } 
}

輸出：

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