Java Character isMirrored() 方法

2024年11月6日 | 阅读时长 5 分钟

Character 类的 isMirrored(char ch) 方法根据 Unicode 规范确定给定（或指定）的字符是否是镜像字符。镜像字符的字形必须水平镜像，以便在文本中从右到左显示。

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。

语法

参数

ch：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）的字符是镜像字符，则返回 true。否则，该方法返回 false。

示例 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.

示例 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 Character isMirrored () 方法

Character 类的 isMirrored(int codePoint) 方法根据 Unicode 规范确定给定（或指定）的字符是否是镜像字符。

镜像字符的字形必须水平镜像，以便在文本中从右到左显示。

语法

参数

codePoint：需要测试的字符的 codePoint。

返回值

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

示例 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;

		}
		
       if(check2){
System.out.print("The second codepoint \'"+codepoint2 + "\' is mirrored. \n");
        }    else{
