Week 4: Writing classes/18. Football match, part 3: Class Match

Finally, write a class to model one football match.

So write a (non-public) class 'Match' with the following properties:
Attributes team1 and team2, with type Team
Attributes of integer type goals1 and goals2
A constructor that takes teams 1 and 2 as parameters (but not goal totals).
Method void addGoal(Team team), which increases the number of goals of the given team by one
Method printStatus(), which prints the game status in the format shown in the example below;


Example output when calling the method printStatus:
FCT - UniFC: 1 - 0

import java.util.Random;

public class Test{
    public static void main(String[] args){
        final Random r = new Random();
        
        
        System.out.println("Testing class Match...");
       
       Team t1 = new Team("FCT");
       Team t2 = new Team("UniFC");
       
       Match match = new Match(t1, t2);
       System.out.println("Match object created!");
       
       for (String fname : new String[] {"team1", "team2", "goals1", "goals2"}) {
           try {
               Field fld = match.getClass().getDeclaredField(fname);
               boolean isPrivate = fld.getModifiers() == 2;
               System.out.println(fname + " is private: " + isPrivate);
           } catch (Exception e) {
               System.out.println("Attribute " + fname + " is not defined");
           }
       }
       
       System.out.println("Starting situation: ");
       match.printStatus();
       
       System.out.println("Adding goals...");
       
       match.addGoal(t1);
       match.printStatus();
       
       match.addGoal(t2);
       match.printStatus();
       
       match.addGoal(t1);

       match.printStatus();
    }

        this.team2 = team2;
        // remember to initialise attributes to avoid nullpointerexception
        this.goals1 = 0;
        this.goals2 = 0;
    }
    
    public void addGoal(Team team) {

Testing class Match...
Match object created!
team1 is private: true
team2 is private: true
goals1 is private: true
goals2 is private: true
Starting situation: 
FCT - UniFC: 0 - 0
Adding goals...
FCT - UniFC: 1 - 0
FCT - UniFC: 1 - 1
FCT - UniFC: 2 - 1
FCT - UniFC: 3 - 1
FCT - UniFC: 3 - 2
