Question

Create a new project in BlueJ. Create two new classes in the project, with the following specifications:

Class name: Part

Fields:

• id (int)
• description (String)
• price (double)
• onSale (boolean)

1 Constructor: takes parameters partId, partDescrip, and partPrice to initialize fields id, description, and price; sets onSale field to false.

Methods: Write get-methods (getters) for all four fields. The getters should be named getId, getDescription, getPrice, and isOnSale.

Answer 1

class Part{
        private int id;
        private String description;
        private double price;
        private boolean onScale;
        public Part(int aId, String aDescription, double aPrice) {
                super();
                id = aId;
                description = aDescription;
                price = aPrice;
                onScale=false;
        }
        public int getId() {
                return id;
        }
        public String getDescription() {
                return description;
        }
        public double getPrice() {
                return price;
        }
        public boolean isOnScale() {
                return onScale;
        }
        
        
}
public class TestPart {
        public static void main(String[] args) {
                Part p =new Part(1, "Brakes", 100);
                System.out.println("Id: "+p.getId());
                System.out.println("Description: "+p.getDescription());
                System.out.println("Price: "+p.getPrice());
        }
}
