Java Character toCodePoint()用法及代碼示例

字符類的 toCodePoint(char high, char low) 方法通常將指定的代理對轉換為其補充的 codePoint 值。上述方法不會驗證給定的代理對。如有必要，調用方必須使用 isSurrogatePair 對其進行驗證。

用法

public static int toCodePoint(char high, char low)

參數

上述方法需要兩個參數：

a.) 高代理代碼點。

b.) 低代理代碼點。

返回值

toCodePoint(char high, char low) 方法從給定的代理對返回補充 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);
    }
  }

輸出：

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);
  }
}

輸出：

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