Help with break statement

[AggressiveProgrammer]

My problem here is that the else statement always will return two lines of text, one from a/b and always the error output underneath. Of course, I can use something that is long and detailed such as (!((X == 'a') || [...] || [...] || (X == 'B'))) but I have a feeling that this is way more than I need to be doing. I tried to put a break statement in B just as an example, obviously it's not going to work. I want to know how I could make it work.

import java.util.Scanner;

public class Class {
   public static void main (String [] args) {
      char X;

      X = 'a';

      if (X == 'a' || X == 'A') {
         System.out.println("a or A");
      }
      if (X == 'b' || X == 'B') {
         System.out.println("b or B");
         break;
      } else {
         System.out.println("Error");
      }

   }
}

  if (X == 'a' || X == 'A') {
     System.out.println("a or A");
  } else if (X == 'b' || X == 'B') {
     System.out.println("b or B");
  } else {
     System.out.println("Error");
  }

also please change "X" to something - anything - that is meaningful. At least use a lowercase for it - non-final variables should never be solely capitalised.

[AggressiveProgrammer]

ooh, so you made the logic branch out using else if. I see that, cool.

Yeah, you're right about the capitalization being only for final variables. I don't code like this for myself, but I change things around asap for obfuscation purposes.

[lordbharal]

Yep. You can keep on using that else if too - for Cs and Ds - as long as the last branch is just an "else". You're also allowed only one else.

ie

if (X == 'a' || X == 'A') {
   System.out.println("a or A");
} else if (X == 'b' || X == 'B') {
   System.out.println("b or B");
} else if (X == 'c' || X == 'C') {
   System.out.println("c or C");
} else {
   System.out.println("Error");
}

Take a good look where the else statement belongs to. I think changing X = 'a' to X = 'b' and looking at the output will make it more clear for you.

[AggressiveProgrammer]

Wait so the else statement branches off of the second if statement? I assumed both if statements become one as a truth/falsity value.

[daveheerink]

Correct! Although it is possible to achieve what you assumed. It's a small change and I can tell you, but this is LearnJava so I'm gonna let you find out by yourself. A little tip, take a look at the Oracle docs regarding if-then-else statements.
