Why does this work:
public String dueDateTypeLetter() {
if (this.dueDateType() == null || this.dueDateType().equals("N")) {
return "";
}
return this.dueDateType();
}
and this doesn't....
public String dueDateTypeLetter() {
if (this.dueDateType().equals("N") || this.dueDateType() == null) {
return "";
}
return this.dueDateType();
}
obviously the difference is the order of checking in the 'if' statement...
I don't really care that I must check in a specific order... It just took me time to understand that the order was important.
