Comma in property files

Question

custc.krtdocument.errors=/properties/error.properties,20

I found this in one of the property files in my java web project, I wonder In above what is the meaning of putting ",20" there??

Answer 1

It indicates list of values or Lists and arrays

Using ',' Commons Configuration has the ability to return easily a list of values. For example a properties file can contain a list of comma separated values

colors.pie = #FF0000, #00FF00, #0000FF

Using Java properties class

  private String[] errs = prop.getProperty("custc.krtdocument.errors").split[","];

Answer 2

It usually indicates that custc.krtdocument.errors will be an array type

@Value("${custc.krtdocument.errors}")
private String[] errors;
