java - How can I check if one value is A or B and another value is A or B? -


i'm trying effect of:

if (firstchoice == || b && secondchoice == || b){     //passes check. }

logically, want pass if first , second choice either or b. syntax valid? there better way it?

you can't == || b; can (but shouldn't, see below):

if ((firstchoice == || firstchoice == b) &&     (secondchoice == || secondchoice == b)) {

that's readable you're going it. breaking on line makes easier follow logic; horizontal scrolling bad thing, , breaking @ && operator readable way.

however, there's way make more readable: create helper method, want.

private boolean isaorb(yourobject choice) {     return choice == || choice == b; }

then if statement be:

if(isaorb(firstchoice) && isaorb(secondchoice)) {

this more readable future readers, including yourself, you're going here.
