代码:
java
import org.apache.commons.lang3.StringUtils;
import static java.lang.Character.UnicodeBlock.*;
/*
* 查询字符串当中是否包含中文
* */
public class text2 {
private static boolean checkStringContainChinese(String checkStr){
if (StringUtils.isNotBlank(checkStr)) {
char[] checkChars = checkStr.toCharArray();
for (int i = 0; i < checkChars.length; i++) {
char checkChar = checkChars[i];
if (checkStringContainChinese(checkChar)) {
return true;
}
}
}
return false;
}
private static boolean checkStringContainChinese(char checkChar) {
// TODO Auto-generated method stub
Character.UnicodeBlock ub = Character.UnicodeBlock.of(checkChar);
if (CJK_UNIFIED_IDEOGRAPHS == ub||CJK_COMPATIBILITY_IDEOGRAPHS==ub||
CJK_COMPATIBILITY_FORMS == ub|| CJK_RADICALS_SUPPLEMENT == ub||
CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A == ub||CJK_UNIFIED_IDEOGRAPHS_EXTENSION_B==ub) {
return true;
}
return false;
}
public static void main(String[] args) {
String a = "和加快速度676";
String b = "";
String c = "121sdhfks";
System.out.println("是否包含中文:"+checkStringContainChinese(a));
System.out.println("是否包含中文:"+checkStringContainChinese(b));
System.out.println("是否包含中文:"+checkStringContainChinese(c));
}
}
