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]+");
