Java 业务规则应用于设置器以限制字符串长度并在超出限制时插入空间

Question

I have this setter method:

        public void setCgp_name(String cgp_name) {
        this.cgp_name = cgp_name;
    }

Basically when the user inserts a long string such as ARG,AUS,BEL,BRA,DNK,FRA,ITA,GBR,USA without any spaces between the commas this info is placed into a table and it will break the boundaries of the table. I am trying to apply a business rule to this setter so that if the user enters something like this: ARG,AUS,BEL,BRA,DNK,FRA,ITA,GBR,USA a space will be added in somewhere to prevent the formatting issue in the table. The word wrapping works when spaces are present but not with long strings.

Answer 1

    public void setCgp_name(String cgp_name) {

        cgp_name = cgp_name.replaceAll(",[ ]*", ", ");

        this.cgp_name = cgp_name;
    }
