Lab 1 Inheritance Instructions Code the classes in your IDE

Lab 1 Inheritance Instructions: Code the classes in your IDE and submit the va files through the Lab 1 submission link. l. Consider using the following card class. public class Card private String name public Card name public Card (String n) name ni public String getName return name; public boolean isExpired return false; public String format return \"Card holder: name

Solution
