I´ve created a function where you add a result for a participant in a event.
Now I want to pass the created object to an addResult-method in my participant class and thereafter add it to an ArrayList in the same class, but I can´t really figure out how to do this. I´ve been stuck on this for a while, and could need some help how to approach this further.
This is what I´ve coded so far for this:
public Participant getParticipant() {
int startNumber = readInt();
boolean participantFound = false;
for (int i = 0; i < allParticipants.size(); i++) {
if (allParticipants.get(i).getStartNumber() == (startNumber)) {
participantFound = true;
return allParticipants.get(i);
}
}
if (!participantFound) {
System.out.println("No participant with number " + startNumber + " exists. " + "\n");
runCommandLoop();
}
return null;
}
public Event getEvent() {
String eventName = norm();
boolean eventFound = false;
for (int a = 0; a < allEvents.size(); a++) {
if (allEvents.get(a).getEventName().equalsIgnoreCase(eventName)) {
eventFound = true;
return allEvents.get(a);
}
}
if (!eventFound) {
System.out.println("No event called " + eventName + " found! ");
runCommandLoop();
}
else {
System.out.println("To many attempts! ");
runCommandLoop();
}
return null;
}
public void addResult() {
System.out.println("Number: ");
Participant p = getParticipant();
if (p == null) {
}
System.out.println("Event: ");
Event e = getEvent();
if (e == null) {
}
System.out.println("Type in the result for " + p.getFirstName() + " " + p.getLastName() + " in "
+ e.getEventName() + ": ");
double result = readDouble();
while (result < 0) {
System.out.println("Must be greater than or equal to zero! Try again: ");
result = readDouble();
}
Result r = new Result();
**// THIS IS WHERE I´M STUCK RIGHT NOW**
r.addResult();
System.out.println("The result " + result + " is now registred");
}
And this is my Participant class:
import java.util.ArrayList;
public class Participant {
public ArrayList<Result> allResults = new ArrayList<>();
private String firstName;
private String lastName;
private String team;
private int startNumber;
public Participant(String firstName, String lastName, String team, int startNumber) {
this.firstName = firstName;
this.lastName = lastName;
this.team = team;
this.startNumber = startNumber;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getTeam() {
return team;
}
public void setTeam(String team) {
this.team = team;
}
public int getStartNumber() {
return startNumber;
}
public void setStartNumber(int startNumber) {
this.startNumber = startNumber;
}
public void addResult(Result r) {
allResults.add(r);
}
public String toString() {
return "\n" + "Name: " + firstName + "\n" + "Last name: " + lastName + "\n" + "Team: " + team + "\n"
+ "Start number: " + startNumber;
}
}
And my Result class:
public class Result {
private double result;
public Result(double result) {
this.result = result;
}
public double getResult() {
return result;
}
public void setResult(double result) {
this.result = result;
}
public void printResult() {
System.out.println(result);
}
}
What you are doing is
Result r = new Result();
**// THIS IS WHERE I´M STUCK RIGHT NOW**
r.addResult();
but I do not see addResult()
Method in Result Class. What you need to do is
p.addResult(r); // p is your Participant
hope this helps
