First thing, <code>super</code> doesn't work the way you have used it. when you extend a class, <code>CarRental</code> in your case, you inherite all <code>public</code> and <code>protected</code> members of that class. so to use a variable of your super class, you dont have to prefix <code>super</code>, you can just use the variable as if the child class holds it. so instead of <pre><code>super.dailyRentalFee = 79.99; </code></pre> use <pre><code>dailyRentalFee = 79.99; // since dailyRentalFee is protected in class CarRental // this will work </code></pre> similarly, <pre><code>super.totalRentalFee = super.dailyRentalFee * super.getRentalDays() + this.dailyChauffeurFee * super.getRentalDays(); </code></pre> should be written as <pre><code>totalRentalFee = dailyRentalFee * getRentalDays() + this.dailyChauffeurFee * getRentalDays(); </code></pre> provided, the method <code>getRentalDays</code> is public in the <code>CarRental</code> class. and about the error you mentioned in @Jeroen's answers' comments, make sure <code>LuxuryCarRental</code> and <code>CarRental</code> are in the same <code>package</code>. To be simple, make sure both files are in the same folder. EDIT: Your code doesn't contain a <code>main</code> method, that is why that error is produced. You should have a <code>main</code> method in your program for it to execute. That is the starting point of all java applications. so define a class with a <code>main</code> method inside and then create a <code>LuxuryCarRental</code> object and perform your computations there. for example, <pre><code>class Sample { public static void main(String[] args) { //this is how all main methods would look LuxuryCarRental luxuryCar = new LuxuryCarRental("A",62020,"SUV",10,true); //call the LuxuryCarRental methods as per your coding requirements } } </code></pre> see, its simpe, <pre><code>class CarRental { //CarRental code } class LuxuryCarRental { //LuxuryCarRental code } class Test { public static void main(String[] args) { LuxuryCarRental luxuryCar = new LuxuryCarRental("A",62020,"SUV",10,true); luxuryCar.display(); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
