Java Character toCodePoint()用法及代码示例

字符类的 toCodePoint(char high, char low) 方法通常将指定的代理对转换为其补充的 codePoint 值。上述方法不会验证给定的代理对。如有必要，调用方必须使用 isSurrogatePair 对其进行验证。

用法

public static int toCodePoint(char high, char low)

参数

上述方法需要两个参数：

a.) 高代理代码点。

b.) 低代理代码点。

返回值

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

例子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

例子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
