Java使用正则表达式判断是否包含中文、英文、数字、自定义符号

    
    private static int matching(String value) {
        value = value.replace(" ", "")
                .replace("#", "")
                .replace("——", "")
                .replace("_", "");
        String regex1 = "[\u4E00-\u9FA5]+";
        String regex2 = "^[A-Za-z0-9]+$";
        //创建一个字符串对象
        int count = 0;
        for (int x = 0; x < value.length(); x++) {
            String single = String.valueOf(value.charAt(x));
            if (single.matches(regex1) || single.matches(regex2)) {
                count++;
            }
        }
        System.out.println("value:" + value.length());
        System.out.println("count:" + count);
        if (value.length() == count) { //不包含特殊字符
            return 0;
        }
        return 1; //包含特殊字符
    }
