Thank you for participating in the study.

Section 1.22 Identification

Activity 1.22.1.

    These code blocks are the ones you saw in the previous question and they all have the same functionality. Among these options which one is preferable?
    🔗
  • public static boolean hasPermission(boolean isAdmin, boolean hasWriteAccess, boolean isAccountActive) {
   if (isAdmin == true) {
      return true;
   }
   if (hasWriteAccess == true) {
      return true;
   }
   if (isAccountActive == true) {
      return true;
   }
   return false;
}
  • This code can be improved!
  • public static boolean hasPermission(boolean isAdmin, boolean hasWriteAccess, boolean isAccountActive) {
  return isAdmin == true || hasWriteAccess == true || 
            isAccountActive ==true; 
}
  • Still can be improved!
  • public static boolean hasPermission(boolean isAdmin, boolean hasWriteAccess, boolean isAccountActive) {
  return isAdmin || hasWriteAccess || isAccountActive; 
}
  • Correct!
