Java判断字符是否汉字

   今天用到了记录下，找到了2种方法

  

   第一种：

  

	 public  boolean isChinese(char c) {  
		  
	        Character.UnicodeBlock ub = Character.UnicodeBlock.of(c);  
	  
	        if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS  
	  
	                || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS  
	  
	                || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A  
	  
	                || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION  
	  
	                || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION  
	  
	                || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) {  
	  
	            return true;  
	  
	        }  
	  
	        return false;  
	  
	}  

  其利用了对应的Character属性进行判断

 

  第二种：根据unicode值范围判断

 

 

 return java.lang.Character.toString('陈').matches("[\\u4E00-\\u9FA5]+");
