java-查询字符串当中是否包含中文

代码:

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)) {
