Find the errors in the following if statements.
a. if (x && y == 0) { x = 1; y = 1; }
b. if (1 <= x <= 10)
System.out.println(x);
c. if (!s.equals("nickels") || !s.equals("pennies")
|| !s.equals("dimes") || !s.equals("quarters"))
System.out.print("Input error!");
d. if (input.equalsIgnoreCase("N") || "NO")
return;
To some advanced users, this may seem simple. However for me it;s hard to pick out! Does anyone want to take a wack at it? Thanks!

Ok, not sure if this is right. I think in b.) it should be changed to f (1 <= x && x <= 10) otherwise it wont work.
In c.) ! means not, so I dont understand what !s.equals("dimes") etc means? that looks like it would translate to not s equals.
a.) doesnt make much sense to me either because what i'm getting from it is : if x and y have a value of 0, x =1 and y=1.
Can someone tell me if my answer (or part of the answer) if true at all? Thanks.
c) is also incorrect but for an entirely different reason (the others don't even syntactically make sense); suppose you want to test something against A and B; suppose that something is C; of course it isn't equals to A or B; but now suppose the something if A; it is definitely equal to A but it isn't equal to B so the or test (||) is still true: A isn't equals to A or B.
kind regards,

Oh, i see, yes that makes sense. So are you saying my other answers are wrong? Not sure where else to go from here with that.
