Java Character toCodePoint() 方法

2024 年 11 月 6 日 | 阅读 2 分钟

toCodePoint(char high, char low) 方法通常将指定的代理对转换为其补充码点值。上述方法不验证给定的代理对。如果需要，调用者需要使用 isSurrogatePair 来验证它。

语法

参数

上述方法需要两个参数

a.) 高位代理码点。

b.) 低位代理码点。

返回值

toCodePoint(char high, char low) 方法从给定的代理对返回补充码点。

示例 1

public class JavaCharactertoCodePointExample1 {
    public static void main(String[] args) {
     // Create two char objects.
	char high = '\ud800';
	char low = '\udd10'; 
     // Converts the specified surrogate pair into its respective supplementary codePoint
        int result = Character.toCodePoint(high, low);	
     // Print the result
	String str= "The result for the above charactetr is given as:"+result;
        System.out.println(str);
    }
  }

输出

The result for the above charactetr is given as:65808

示例 2

public class JavaCharactertoCodePointExample2 {
    public static void main(String[] args) {
         // Create four char objects.
	char high1 = '\ud900';
	char low1 = '\ud120'; 
        char high2 = '\ud560';
	char low2 = '\ud320'; 
     // Converts the specified surrogate pair into its respective supplementary codePoint
        int result1 = Character.toCodePoint(high1, low1);
        int result2 = Character.toCodePoint(high2, low2);        
     // Print the result.
	String str1 = "The result for the above character is given as:"+result1;
        String str2 = "The result for the above character is given as:"+result2;
        System.out.println(str1);
        System.out.println(str2);
  }
}

输出

The result for the above character is given as:324896
The result for the above character is given as:-624864
