Unary operators

[dhruv simaria]

well Simon Roberts in his book has mentioned, that for Unary operators ,2 rules aply. One of them being that if the operand is byte,short or a char,it is converted to an int.
Using this rule
When you run this code ,the ouput should be type mismatch, as we can't convert int value to char type without casting,but surprisingly when you run this code you get the answer as - The value is b
Why?

class Achtung {
public static void main (String args[]){
char A ='a';
++A;
System.out.println("The  value is "+A);
                                        }
              }

Hi, welcome to JavaRanch. This particular forum is intended for discussion about JavaRanch itself, not for questions about the Java language. I am moving this post to Java in General (Beginner), which is a good place for your questions about the language.
