Invalid method declaration, return type required
- by Brett Steen
I am getting an error at public Rectangle(double width, double height){ saying that it's an invalid method declaration, return type required. I'm not sure how to fix it. These are also my instructions for my assignment:
Write a super class encapsulating a rectangle. A rectangle has two attributes representing the width and the height of the rectangle. It has methods returning the perimeter and the area of the rectangle. This class has a subclass, encapsulating a parallelepiped, or box. A parallelepiped has a rectangle as its base, and another attribute, its length. It has two methods that calculate and return its area and volume.
`public class Rectangle1
{
private double width;
private double height;
public Rectangle1(){
}
public Rectangle(double width, double height){
this.width = width;
this.height = height;
}
public double getWidth(){
return width;
}
public void setWidth(double width) {
this.width = width;
}
public double getHeight(){
return height;
}
public void setHeight(double height){
this.height = height;
}
public double getArea(){
return width * height;
}
public double getPerimeter(){
return 2 * (width + height);
}
}
public class TestRectangle {
public static void main(String[] args) {
Rectangle1 rectangle = new Rectangle1(2,4);
System.out.println("\nA rectangle " + rectangle.toString());
System.out.println("The area is " + rectangle.getArea());
System.out.println("The perimeter is " +
rectangle.getPerimeter());
}
}`
