Question

For this problem, we are going to revisit the Online Company exercise from lesson 3. In lesson 3, we created 3 classes, a superclass Company, a subclass OnlineCompany and a runner class CompanyTester. You can take your solutions from lesson 3 for the Company and OnlineCompany, but we are going to redesign the CompanyTester in this exercise.

Your task is to create a loop that will allow users to enter companies that will then get stored in an ArrayList. You should first prompt users for the company name. If the user enters exit, then the program should exit and print the object using the toString.

After prompting for the name, you prompt the user if it is an online company. If so, ask for a website address, otherwise ask for the street address, city, and state. You will then create the Company or OnlineCompany object and insert it into the ArrayList.

Sample output:

Please enter a company name, enter 'exit' to quit: CodeHS
Is this an online company, 'yes' or 'no': yes
Please enter the website address: www.codehs.com
Please enter a company name, enter 'exit' to quit: Uber
Is this an online company, 'yes' or 'no': no
Please enter the street address: 555 Market Street
Please enter the city address: San Fransisco
Please enter the state address: CA
Please enter a company name, enter 'exit' to quit: exit

public class Company {

// Set missing values to null
public Company(String name){
this.name = name;

}
public Company(String name, String streetAddress, String city, String state){
this.name = name;
this.streetAddress = streetAddress;
this.city = city;
this.state = state;

}

public String getName(){
return name;
}

/**
* Example output:
* 123 Main St
* Springfield, OH
*/
public String address(){
return streetAddress + '\n' + city + ", " + state;
}

/**
* Example output:
* Widget Company
* 123 Main St
* Springfield, OH
*/
public String toString(){
return name + '\n' + streetAddress + '\n' + city + ", " + state;
}
}

public class OnlineCompany extends Company{

private String webAddress;

public OnlineCompany(String name, String webAddress){
super(name, "it", "does not have", "an address");
this.webAddress = webAddress;
}

//Return the website address
@Override
public String address(){
return webAddress;
}

/**
* Remember To get name from superclass, use super.getName()
*
* Example Output:
* CodeHS
* www.codehs.com
*/
@Override
public String toString(){
return super.getName() + '\n' + webAddress;
  
}
}

## the code below is the one I need to complete

public class CompanyTester
{
public static void main(String[] args)
{
// Start here!
