difference between size max value and min value max value

Question

I want to do some domain validation in my object I am having one integer  now my question is  if I write  Min SEQ MIN VALUE   Max SEQ MAX VALUE  private Integer sequence   and   Size min   1  max   NAME MAX LENGTH   private Integer sequence   If it s integer which one is proper for domain validation  can anybody explain me what is the difference between them   Thanks

Min and  Max are used for validating numeric fields which could be String representing number   int  short  byte etc and their respective primitive wrappers     Size is used to check the length constraints on the fields   As per documentation  Size supports String  Collection  Map and arrays while  Min and  Max supports primitives and their wrappers  See the documentation

From the documentation I get the impression that in your example it would be intended to use   Range min  SEQ MIN VALUE  max  SEQ MAX VALUE    Checks whether the annotated value lies between  inclusive  the specified minimum and maximum  Supported data types  BigDecimal  BigInteger  CharSequence  byte  short  int  long and the respective wrappers of the primitive types
