Java Character isMirrored()用法及代码示例

Character 类的 isMirrored(char ch) 方法确定给定(或指定)字符是否按照 Unicode 规范进行镜像。镜像字符的字形必须水平镜像，以便在文本中显示时，它们是从右到左的。

注意：上述方法不能用于处理增补字符。为了处理增补字符，我们可以使用 isMirrored(int) 方法。

用法

public static boolean isMirrored(char ch)

参数

ch: 是需要测试镜像属性的字符。

返回值

isMirrored(char ch) 方法返回一个布尔值，即如果给定(或指定)字符被镜像，则为真。否则，该方法返回 false。

例子1

import java.util.Scanner;
public class JavaCharacterIsMirroredExample1 {
   public static void main(String[] args) {
    // Ask the user for the first input.
	System.out.print("Enter the first character:");
    // Use Scanner class to get the user input.
	Scanner s1 = new Scanner(System.in);
    // Gets a single character.
	char[] value1 = s1.nextLine().toCharArray();
         for (char ch1:value1) {
    // Check whether the user input is mirrored or not.
	boolean check1 = Character.isMirrored(ch1);
    // Print the result.
	if (check1) {
	System.out.println("The first input \'" + ch1 + "\' is mirrored.");
	} else {
	System.out.println("The first input \'" + ch1 + "\' is not mirrored.");
			}
        System.out.print("Enter the second character:");
    // Use Scanner class to get the user input.
	Scanner s2 = new Scanner(System.in);
    // Gets a single character.
	char[] value2 = s2.nextLine().toCharArray();
         for (char ch2:value2) {
    // Check whether the user input is mirrored or not.
	boolean check2 = Character.isMirrored(ch2);
    // Print the result.
	if (check2) {
	System.out.println("The second input \'" + ch2 + "\' is mirrored.");
	} else {
	System.out.println("The second input \'" + ch2 + "\' is not mirrored.");
	         }
                    }
             }
     }
}

输出：

Enter the first character:*
The first input '*' is not mirrored.
Enter the second character:[
The second input '[' is mirrored.

例子2

public class JavaCharacterIsMirroredExample2 {
    public static void main(String[] args) {
      // Create three char primitives ch1, ch2 and ch3.
      char ch1, ch2, ch3;

      // Assign the values to ch1, ch2 and ch3.
      ch1 = '{';
      ch2 = '^';
      ch3 = '&';
      // Create three boolean primitives b1, b2 and b3.
      boolean b1, b2, b3;
      // Check whether ch1, ch2 and ch3 are mirrored and assign the results to b1, b2 and b3.
      b1 = Character.isMirrored(ch1);
      b2 = Character.isMirrored(ch2);
      b3 = Character.isMirrored(ch3);
      String str1 = "The first character '"+ch1 +"' is a mirrored character:" + b1;
      String str2 = "The second character '"+ch2 +"' is a mirrored character:" + b2;
      String str3 = "The third character '"+ch3 +"' is a mirrored character:" + b3;
      // Print the values of b1, b2 and b3.
      System.out.println( str1 );
      System.out.println( str2 );
      System.out.println( str3 );
   }
}

输出：

The first character '{' is a mirrored character:true
The second character '^' is a mirrored character:false
The third character '&' is a mirrored character:false

Java 字符 isMirrored() 方法

Character 类的 isMirrored(int codePoint) 方法确定给定(或指定)字符是否按照 Unicode 规范进行镜像。

镜像字符的字形必须水平镜像，以便在文本中显示时，它们是从右到左的。

参数

codePoint:codePoint 是需要测试的字符。

返回值

isMirrored(int codePoint) 方法返回一个布尔值，即如果给定(或指定)字符被镜像，则返回 true。否则，该方法返回 false。

例子1

public class JavaCharacterisMirroredExample_1 {
    public static void main(String[] args) {
     // Initialize the four codepoints.
	 int codepoint1 = 93;
        int codepoint2 = 121;
        int codepoint3 = 168;
        int codepoint4 = 199;
