Question

The purpose of this assignment is to read in a file called nfl.txt which has different types of players in it, quarterbacks and recievers which have 4 of the same fields, then quarterback has 3 others and reciever 2. Make three classes, Player, Quarterback extends Player, and Reciever extends Player. Then a test program called Prog6. The problem I am running into is I think on the Prog6 tester... It will not output the information I want it to, actually when I run the program it just terminates without any errors. I need this formatted in a specific format but I would just be happy with getting an output of the players and their stats.

(Prog6 http://codepad.org/tsYrOKyy )

(Player http://codepad.org/4UgIJdQL )

(Quarterback http://codepad.org/wblgYZAh )

(Receiver http://codepad.org/1z39vWMK )

(nfl.txt http://codepad.org/8Pz3N5Qz )

Explanation / Answer

Here you go :

import java.util.*;

import java.io.*;

public class Prog6

{

public static void main(String[] args)

{

String fName;

String lName;

String position;

String team;

int completions = 0;

int attempts = 0;

int yards = 0;

int receptions = 0;

final int MAX_PLAYERS = 20;

Scanner inFile = null;

Player players[] = new Player[MAX_PLAYERS];

try

{

inFile = new Scanner( new File ( "nfl.txt" ) );

}

catch( FileNotFoundException e)

{

System.err.println( "Error: file not found" );

}

int count=0;

while( inFile.hasNext() )

{

fName = inFile.next();

lName = inFile.next();

team = inFile.next();

position = inFile.next();

if( position.equals("QB") )

{

completions = inFile.nextInt();

attempts = inFile.nextInt();

yards = inFile.nextInt();

players[count]=new Quarterback(fName,lName,team,position,completions,attempts,yards);

}

else

{

receptions = inFile.nextInt();

yards = inFile.nextInt();

players[count]=new Receiver(fName,lName,team,position,receptions,yards);

}

for(int i = 0; i < players.length ; i++)

{

if( players[i] instanceof Quarterback )

{

System.out.println( players[i].getfName() + players[i].getlName() + players[i].getTeam() + players[i].getPosition() + ( (Quarterback) players[i]).getCompletions() + (( Quarterback ) players[i]).getAttempts() + ((Quarterback) players[i]).getYards());

}

}

for( int j = 0; j < players.length ; j++)

{

if( players[j] instanceof Receiver)

{

System.out.println( players[j].getfName() + players[j].getlName() + players[j].getTeam() + players[j].getPosition() + ((Receiver) players[j]).getReceptions() + ((Receiver) players[j]).getYards());

}

}

}

}

}
