Error showing int is equal to a boolean object

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

You can't compare int and double.
You need just if(isStudent() || isChild()) (inside these functions you already "checked whether the age given was between some given numbers").

Try this instad of if(age == (isStudent() || isChild())

if(true == ((isStudent() || isChild()). isStudent and isChild methods return type shold be boolean.

You can't apply equal method from integer.

instead of if(age.equals(isChild())) apply similer way as if(true == ((isStudent() || isChild())

int and boolean are two different types, and can never be equal to each other. An int has 2^32 values, whereas a boolean has only two : true and false.

Your methods should be isStudent(int age) and isChild(int age). They would return true or false depending on the age argument.

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.
