使用了两种方法进行判断
Java代码
- /
- * 把中文转成Unicode码
- * @param str
- * @return
- */
- public String chinaToUnicode(String str){
- String result=“”;
- for (int i = 0; i < str.length(); i++){
- int chr1 = (char) str.charAt(i);
- if(chr1>=19968&&chr1<=){
//汉字范围 \u4e00-\u9fa5 (中文) - result+=“\\u” + Integer.toHexString(chr1);
- }else{
- result+=str.charAt(i);
- }
- }
- return result;
- }
- /
- * 判断是否为中文字符
- * @param c
- * @return
- */
- 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;
- }
Java代码
- static String string2Unicode(String s) {
- try {
- StringBuffer out = new StringBuffer(“”);
- byte[] bytes = s.getBytes(“unicode”);
- for (int i = 2; i < bytes.length - 1; i += 2) {
- out.append(“u”);
- String str = Integer.toHexString(bytes[i + 1] & 0xff);
- for (int j = str.length(); j < 2; j++) {
- out.append(“0”);
- }
- String str1 = Integer.toHexString(bytes[i] & 0xff);
- out.append(str);
- out.append(str1);
- out.append(” “);
- }
- return out.toString().toUpperCase();
- }
- catch (UnsupportedEncodingException e) {
- e.printStackTrace();
- return null;
- }
- }
- static String unicode2String(String unicodeStr){
- StringBuffer sb = new StringBuffer();
- String str[] = unicodeStr.toUpperCase().split(“U”);
- for(int i=0;i
- if(str[i].equals(“”)) continue;
- char c = (char)Integer.parseInt(str[i].trim(),16);
- sb.append(c);
- }
- return sb.toString();
- }
