Question

That’s my confirmBooking method and im trying to check whether age is equal to a student or child so i can apply discounts wherever needed using an if statement. Also my boolean value is because i checked whether the age given was between some given numbers to determine whether it was a child or student. I get this error Customer.java [line: 41]
line 41 is if(age == (isStudent() || isChild()))

Error: The operator == is undefined for the argument type(s) int,
boolean

Could someone explain why?

 public double confirmBooking(){
    double standardTicketPrice = 56.0;
    double standardMealPrice = 30.0;

    if(age == (isStudent() || isChild())){
    return standardTicketPrice / 2.0;
    }else{
    return standardTicketPrice * (20.0/100.0); 
    }

    if(age.equals(isChild())){
      return standardMealPrice / 2.0;
    }else{
     return standardMealPrice * (10.0/100.0); 
    }
  }// end method confirmBooking

Answer 1

Primitive types are compared with ==. You can’t invoke the equals method on a primitive type. Primitive types are not objects. Another error is that you are directly comparing boolean and int value. They are not compatible.
