输入只能为中文字符和英文解决方法

public class TestInputIsChineseOrEnglish {    public static void main(String[] args) {    String string = null;    Scanner scanner = new Scanner(System.in);    do{     string= scanner.nextLine();    for(int i=0; i<string.length(); i++)        if(isEnglish(string.charAt(i)) == false && isChinese(string.charAt(i)) == false){        System.out.println("error");break;}    System.out.println("correct");        }while(string.equals("exit") == false);//要退出请输入exit        }    public static boolean isEnglish(Character c){    return c.toString().matches("\\p{ASCII}");//0---127    }        public static 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;    }}
------解决方案--------------------
k3...好厉害！我来解释下
主函数输入一行字符
进入判断
把字符串里字符一个一个取出来charAt(i)
用正则判断是否为英文isEnglish(Character c)，是否为中文isChinese(char c)
如果是英文或者中文字符的话打印correct，否则打印error。
不过我觉得英文匹配"[a-zA-Z]+"合适点
