I just need help on this last step! Write a method called havePlayedTogether(String teamA, String teamB) in the League class that returns a boolean indicating whether or not the teams with the given names have played together or not. You should make use of the gamesPlayed array that you just filled in. Once completed, append the following code to the LeagueTestProgram and compile/run it.
Here's some of my code:
public class League
{
private String name;
private int teamCount;
private Team[] teams;
private int [] [] gamesPlayed = new int[8][8];
public String getName() { return(name); }
public Team[] getTeams() { return(teams); }
public void setName(String aName) { name = aName; }
public League(String aName) {
name = aName;
teamCount = 0;
teams = new Team[8]; //This does not actually make any Team objects
}
//This is the toString method that specifies the appearance of the League
public String toString() {
return("The " + name + " league with " + teamCount + " teams.");
}
//This method adds a new team to the league
public int addTeam(Team aTeam) {
if (teamCount
teams[teamCount++] = aTeam;
return teamCount;
}
return -1;
}
//This method prints out all of the teams
public void showTeams() {
for(int i=0; i System.out.println(teams[i].toString()); } /****************** For LeagueTester1 *******************************/ //Record Win and Loss and updates public void recordWinAndLoss(Team winner, Team loser) { winner.setWins(winner.getWins() + 1); loser.setLosses(loser.getLosses() + 1); int x = indexOf(winner); int y = indexOf(loser); gamesPlayed[x][y] += 1; gamesPlayed[y][x] += 1; } //Record a Tie game and updates public void recordTie(Team teamA, Team teamB) { teamA.setTies(teamA.getTies() + 1); teamB.setTies(teamB.getTies() + 1); int x = indexOf(teamA); int y = indexOf(teamB); gamesPlayed[x][y] += 1; gamesPlayed[y][x] += 1; } //Find the team with the given name. If none exists, return null public Team teamWithName(String aName) { for(int i=0; i if (teams[i].getName().equals(aName)) return teams[i]; } return null; } //Record Win and Loss public void recordWinAndLoss(String winner, String loser) { Team winningTeam, losingTeam; if ((winningTeam = this.teamWithName(winner)) == null) { System.out.println("Invalid Team name: " + winner); return; } if ((losingTeam = this.teamWithName(loser)) == null) { System.out.println("Invalid Team name: " + loser); return; } recordWinAndLoss(winningTeam, losingTeam); } //Record a Tie game public void recordTie(String teamAName, String teamBName) { Team teamA, teamB; if ((teamA = this.teamWithName(teamAName)) == null) { System.out.println("Invalid Team name: " + teamAName); return; } if ((teamB = this.teamWithName(teamBName)) == null) { System.out.println("Invalid Team name: " + teamBName); return; } recordTie(teamA, teamB); } //Return the total number of games played in the League public int totalGamesPlayed() { int total=0; for (int i=0; i total += teams[i].gamesPlayed(); return total/2; } //Return the team with the most points public Team firstPlaceTeam() { Team best; if (teamCount == 0) return null;//If there are no teams, then no team is in first place best = teams[0]; for (int i=1; i if (best.totalPoints() best = teams[i]; } return best; } //Return the team with the least points public Team lastPlaceTeam() { Team worst; if (teamCount == 0) return null;//If there are no teams, then no team is in last place worst = teams[0]; for (int i=1; i if (worst.totalPoints() > teams[i].totalPoints()) worst = teams[i]; } return worst; } //Returns the team who played the most public Team teamMostPlayed() { Team most; if (teamCount == 0) return null; most = teams[0]; for (int i=1; i if (most.gamesPlayed() most = teams[i]; } return most; } //Returns undefeated teams public Team[] undefeated() { int count= 0; for(int i = 0; i { if(teams[i].getLosses() == 0) { count = count + 1; } } Team[] undefeated = new Team[count]; count = 0; for(int i = 0; i { if(teams[i].getLosses() == 0) { undefeated[count] = teams[i]; count = count + 1; } } return undefeated; } //returns index of specific team of a league public int indexOf(Team t) { for(int i=0; i { if(teams[i] == t) return i; } return -1; } //This method prints out a table showing which teams played which other teams public void showTable() { System.out.println(" 0 1 2 3 4 5 6 7 "); System.out.println(" -------------------------------"); for(int row=0; row { System.out.print(row +" | "); for(int col=0; col { System.out.print(gamesPlayed[row][col] + " | "); } System.out.println(" -------------------------------"); } for(int i=0; i System.out.println(i + " = " + teams[i].getName()); } public class League { private String name; private int teamCount; private Team[] teams; private int [] [] gamesPlayed = new int[8][8]; public String getName() { return(name); } public Team[] getTeams() { return(teams); } public void setName(String aName) { name = aName; } public League(String aName) { name = aName; teamCount = 0; teams = new Team[8]; //This does not actually make any Team objects } //This is the toString method that specifies the appearance of the League public String toString() { return("The " + name + " league with " + teamCount + " teams."); } //This method adds a new team to the league public int addTeam(Team aTeam) { if (teamCount teams[teamCount++] = aTeam; return teamCount; } return -1; } //This method prints out all of the teams public void showTeams() { for(int i=0; i System.out.println(teams[i].toString()); } /****************** For LeagueTester1 *******************************/ //Record Win and Loss and updates public void recordWinAndLoss(Team winner, Team loser) { winner.setWins(winner.getWins() + 1); loser.setLosses(loser.getLosses() + 1); int x = indexOf(winner); int y = indexOf(loser); gamesPlayed[x][y] += 1; gamesPlayed[y][x] += 1; } //Record a Tie game and updates public void recordTie(Team teamA, Team teamB) { teamA.setTies(teamA.getTies() + 1); teamB.setTies(teamB.getTies() + 1); int x = indexOf(teamA); int y = indexOf(teamB); gamesPlayed[x][y] += 1; gamesPlayed[y][x] += 1; } //Find the team with the given name.

I just need help creating the method and editing the bottom,
