Question

Create an abstract method resize for class Shape. Implement the method for classes Rectangle and Circle. The method resizes objects of the two classes by a factor provided as parameter.

Answer 1

The student is asking about creating an abstract method called resize in the class Shape and implementing it in the Rectangle and Circle classes. Here's an example of how the method can be implemented.

Step-by-step explanation:

The subject of this question is Computers and Technology. The student is asking about creating an abstract method called resize in the class Shape and implementing it in the Rectangle and Circle classes. The resize method should resize objects of the two classes by a factor provided as a parameter.

Here's an example of how the method can be implemented:

public abstract class Shape {
public abstract void resize(double factor);
}

public class Rectangle extends Shape {
private double width;
private double height;

public void resize(double factor) {
width *= factor;
height *= factor;
}
}

public class Circle extends Shape {
private double radius;

public void resize(double factor) {
radius *= factor;
}
}

In the example, the resize method is defined as an abstract method in the Shape class and implemented in the Rectangle and Circle classes to resize the objects based on the provided factor.
