[java] difference between @size(max = value ) and @min(value) @max(value)

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.

package com.mycompany;

import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

public class Car {

    @NotNull
    private String manufacturer;

    @NotNull
    @Size(min = 2, max = 14)
    private String licensePlate;

    @Min(2)
    private int seatCount;

    public Car(String manufacturer, String licencePlate, int seatCount) {
        this.manufacturer = manufacturer;
        this.licensePlate = licencePlate;
        this.seatCount = seatCount;
    }

    //getters and setters ...
}

@NotNull, @Size and @Min are so-called constraint annotations, that we use to declare constraints, which shall be applied to the fields of a Car instance:

manufacturer shall never be null

licensePlate shall never be null and must be between 2 and 14 characters long

seatCount shall be at least 2.

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
