Verify if Double is empty

I'm developing a web application and want to validate a Double.

Code:

@Min(0)
@Column(nullable=false)
private Double preco;

Someone can help me?

you can verify it in the getter

private Double preco;

@Column(nullable=false)
public Double getPreco () {
if(preco < 0) {
return 0 ;
} else {
return title ;
}

}

Hi,

What exactly do you mean by "if Double is empty"? Is this to say that your value may not be null? If so, you can use the @NotNull constraint. You may also consider to use a primitive double instead of the wrapper type Double.
