Java code question

Question

How do I change:

} else if(dia == 2) {
foamwidth = dia12;

dia == 2 to be able to have the 2 as a range? ex. if dia == 2-5 (2, 3, 4, or 5) But I want to use it for more than just a few numbers, and I didn't want to type each individual number, just use a range somehow?

Answer 1

if (dia >= 2 && dia <= 5)

Answer 2

Gotcha, thank you very much :)
