All i need is for someone to add the appropriate comments to make this code accurate. Simply label constructors, class variables, say what methods do, point out class changes, etc. Just add comments :)

public class Client {

String companyName;

String companyId;

String billingAddress;

String billingCity;

String billingState;

public Client(String companyName, String companyId, String billingAddress, String billingCity,

String billingState) {

this.companyName = companyName;

this.companyId = companyId;

this.billingAddress = billingAddress;

this.billingCity = billingCity;

this.billingState = billingState;

}

}

HourlyClient.java file:

public class HourlyClient extends Client{

double hoursBilled;

double hourlyRate;

public HourlyClient(String companyName, String companyId, String billingAddress, String billingCity,

String billingState, double hoursBilled, double hourlyRate) {

super(companyName, companyId, billingAddress, billingCity, billingState);

this.hoursBilled = hoursBilled;

this.hourlyRate = hourlyRate;

}

public double billingDue() {

return hoursBilled * hourlyRate ;

}

}
