Issue with expressions, and or not

}else if (j==1){

is it possible to use the and or and not type questions on numbers, or can they only be used as true/false

i.e I'd like to be able to say in java code

if the int j is equal to 0 or 1, colour the brick red
but I can only seem to use ==, I'd can use less than or equal too 1 because there are more conditions that will contradict that later

As is stands I have to put in the case for each value of j from 0 to 9.

thank you all
