> An existing constraint can have several implementations of different types. The following commands will create two implementations of the {{Max}} constraints: one for type {{Number}} and one for {{String}} :
> {code}
> constraint-new-validator --named MaxValidatorForNumber --type Number --targetConstraint Max
> constraint-new-validator --named MaxValidatorForString --type String --targetConstraint Max
> {code}
> The generated code would look like this for Number :
> {code}
> public class MaxValidatorForString implements ConstraintValidator<Max, Number> {
>   @Override
>   public void initialize(URL url) {
>   }
>   @Override
>   public boolean isValid(Number value, ConstraintValidatorContext context) {
>     return false;
>   }
> }
> {code}
> And like that for String :
> {code}
> public class MaxValidatorForString implements ConstraintValidator<Max, String> {
>   @Override
>   public void initialize(URL url) {
>   }
>   @Override
>   public boolean isValid(String value, ConstraintValidatorContext context) {
>     return false;
>   }
> }
> {code}
