这是挑战艺术天分的好机会。下面有一组类和接口的声明。你的任务是画出类的图表。使用虚线来表示实现并以实线来表示继承。
已知：
1)public interface Foo { }
public class Bar implements Foo { } 2)public interface Vinn { }
public abstract class Vout implements Vinn { } 3)public abstract class Muffie implements Whuffie { }
public class Fluffie extends Muffie { }
public interface Whuffie { } 4)public class Zoop { }
public class Boop extends Zoop { }
public class Goop extends Boop { } 5)public class Gamma extends Delta implements Epsilon { }
public interface Epsilon { }
public interface Beta { }
public class Alpha extends Gamma implements Beta { }
public class Delta { }
