Consider the following classes:
public abstract class Cat {
private int age;
private double weight;
private double top_speed;
public void run(double newSpeed) { ... }
private void eat(double portionSize) { ... }
// ... -> getXXX() and setXXX() methods here }
}
public class Cheetah extends Cat {
private String type;
public Cheetah(int age, double wt, double sp, String type) {
this.type = type;
setAge(age);
setWeight(wt);
setTopSpeed(sp);
}
private void run(double newSpeed) { ... }
public void camouflage() { ... } // ... ->
//
getXXX()
//
and setXXX() methods here }
}
Which design principles are violated by these classes? Explain it and then correct it
