Question

write a parent class that describes a parcel (like a package, as shown below) and a child class that describes an overnight parcel. Use the provided Address class.

A parcel is described by:

• id (which might contain numbers and letters)
• weight (described as the number of pounds; a parcel could be less than 1 pound)
• destination address (uses the provided class)

An overnight parcel is described by id, weight, destination address and also:

• whether or not a signature is required upon delivery

public class Address {

private String name, street, city, state, zip;

public Address(String name, String street, String city, String state, String zip) {

this.name = name;

this.street = street;

this.city = city;

this.state = state;

this.zip = zip;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getStreet() {

return street;

}

public void setStreet(String street) {

this.street = street;

}

public String getCity() {

return city;

}

public void setCity(String city) {

this.city = city;

}

public String getState() {

return state;

}

public void setState(String state) {

this.state = state;

}

public String getZip() {

return zip;

}

public void setZip(String zip) {

this.zip = zip;

}

@Override

public String toString() {

return name + "\n" + street + "\n" + city + ", " + state + " " + zip;

}

}
