How to set int variable to number-number

Question

I'm pretty new to Java. I'm making a class for a card. The face is the number of the card, and can only be 1-13. I'm trying to validate it by setting f to 1-13. I wanted to simply do this:

public void setFace(int f)
   {

    f int >= 1 && f <= 13);
   }

Obviously, you can't do that. How do would I simply set f to the numbers 1-13? Thanks for any help!

You're going about validation the wrong way. You should check whether the number is in the valid range and do something if it isn't, not set it equal to all the valid numbers. — user2357112

I would do in this way

public void setFace(int f) {

if(f < 1 || f > 13)
{
   throw new IllegalArgumentException("Invalid face value "+f+" face must be between 1-13");
}
}
