Java Character getName()用法及代碼示例

getName(int codePoint) 方法返回指定字符的 Unicode 名稱，如果未分配 codePoint，則返回 null。如果 Unicode 數據文件沒有為指定的字符指定名稱，則返回的名稱與表達式的結果相同。

Character.UnicodeBlock.of(codePoint).toString().replace('-'), '  ')+"  "+Integer.toHexString(codePoint).toUpperCase(Loale.ROOT);

用法

public static string getName(int codePoint)

參數

上述方法隻需要一個參數：

代碼點：它是字符(Unicode 代碼點)

返回值

如果 codePoint 未分配，則為字符或 null。

例子1

public class JavaCharactergetNameExample1 {
	public static void main(String[] args) {
		  // Declare the codePoints
		     int codepoint = 00;     
		  // Get the Unicode name of the specified character codePoint
		     String result = Character.getName(codepoint);
		 // Print the result
		     System.err.println("The first character '" + (char)codepoint + "' has the unicode name as:" + result);
	     }
	}

輸出：

The first character ' ' has the Unicode name as:NULL

	  // Declare the codePoints
	     int codepoint1 = 93;
	     int codepoint2 = 69;
	  // Get the Unicode name of the specified character codePoint
	     String result1 = Character.getName(codepoint1);
	     String result2 = Character.getName(codepoint2);
	 // Print the result
	     System.err.println("The character '" + (char)codepoint1 + "' has the unicode name as:" + result1);
	     System.err.println("The character '" + (char)codepoint2+ "' has the unicode name as:" + result2);
     }
}

輸出：

The character ']' has the unicode name as:RIGHT SQUARE BRACKET
The character 'E' has the unicode name as:LATIN CAPITAL LETTER E

例子3

public class JavaCharactergetNameExample3 {
	public static void main(String[] args) {
	  // Declare the codePoints
		int codepoint1 = 80;
		int codepoint2 = 55;
		int codepoint3 = 110;
		int codepoint4 = 780;
	 // Get the Unicode name of the specified character codePoint
		String result1 = Character.getName(codepoint1);
		String result2 = Character.getName(codepoint2);
		String result3 = Character.getName(codepoint3);
		String result4 = Character.getName(codepoint4);
       // Print the result
System.err.println("The first character '" + (char)codepoint1 + "' has the unicode name as:" + result1);
System.err.println("The second character '" + (char)codepoint2+ "' has the unicode name as:" + result2);
System.err.println("The third character '" + (char)codepoint3+ "' has the unicode name as:" + result3);
System.err.println("The fourth character '" + (char)codepoint4+ "' has the unicode name as:" + result4);
	     }
