Hi I am confused on what I need to do next on this project I have
Here is what I have to do
Problem overview:
You are to write programs to help manage and provide reports for a small bowling league.
Input specifications:
Input will consist of a text file that is comma delimited. Each record will consist of bowler number, bowler first score, bowler second score, bowler third score. You are not allowed to modify the input file in any way.
Processing requirement:
Each record’s information will be used to instantiate a “Bowler” type object. The Bowler object will have the following attributes: bowlerNumber, score 1, score 2 and score 3. All attributes are to be integers. You will need to provide the ‘set’ and ‘get’ methods for each attribute. You will also need to provide at least 1 constructor method for the Bowler class.
Output specifications:
Your program needs to allow the user to choose between multiple reports.
- Display file information
- Display file information plus the average score for each bowler
- Display file information plus the team totals for each game and a grand total for the team’s series total.
and this is the code that I have done so far
public class Bolwer
{
int bowlerNumber;
int score_1;
int score_2;
int score_3;
//creates a constructor method
public Bowler (int number, int s1, int s2, int s3)
{
bowlerNumber = number;
score_1 = s1;
score_2 = s2;
score_3 = s3;
}
//sets the bowler\'s number
public void bowlerNumber(int number)
{
bowlerNumber = number;
}
//sets the first score
public void score_1 (int s1)
{
score_1 = s1;
}
//sets the second score
public void score_2 (int s2)
{
score_2 = s2;
}
//sets the third score
public void score_3 (int s3)
{
score_3 = s3;
}
//gets the bowler number
public int bowlerNumber()
{
return number;
}
//gets the first score
public int score_1()
{
return s1;
}
//gets the second score
public int score_2()
{
return s2;
}
//gets the third score
public int score_3()
{
return s3;
}
public double average()
{
return (s1+s2+s3) / 3;
}
}
import java.io.*;
import java.util.Arrays;
import java.util.Scanner;
public class BowlerDemo
{
public static void main(String [] agrs) throws IOException
{
int bowlerNumber;
int score_1;
int score_2;
int score_3;
ArrayList info = new ArrayList();
//identifies the file and opens it
File file = new File (\"Scores.txt\");
//creates a new scanner type object
Scanner inputfile = new Scanner(file);
while (inputfile.hasNext())
{
String stats = inputfile.nextLine();
info.add(stats);
}
try
{
//opens the file
PrintWriter outputFile = new PrintWriter(\"Mid-Term.txt\");
int sz = info.size();
for (int i = 0; i < sz; i++)
{
outputfile.println(info.get(i).toString());
}
outputfile.close();
}
catch (Exception e)
{
System.out.pintln(\"The file cant be created\");
}
//see if the values were assigned correctly
System.out.println(bowlerNumber + score_1 + score_2 + score_3);
//creates the student variable
Bowler b = new Bowler(bowlerNumber, score_1, score_2, score_3);
//closes the files
outputFile.close();
inputfile.close();
//tells the user a file was created with the info requested
System.out.println(\"Data was written to a file called Mid-Term.txt.\");
}
}
and the data that is in the file that I am trying to read is
101, 123, 133, 165, 102, 202, 175, 220, 103, 155, 170, 140, 104, 123, 111, 99, 105, 75, 127, 133, 201, 195, 202, 187, 202, 188, 167, 175, 203, 145, 155, 165, 204, 165, 180, 133, 205, 140, 130, 125, 301, 100, 175, 90, 302, 130, 77, 120, 303, 200, 230, 193, 304, 178, 188, 193, 305, 155, 156, 157, 401, 160, 140, 155, 402, 170, 190, 185, 403, 210, 202, 233, 404, 105, 121, 133, 405, 145, 165, 185
I know I need to put in a \"split\" and proabbly use an \"ArrayList\", but I am not sure where would be a good spot to put the \"split\" in and whenever I try and put the \"ArrayList\" in my program it keeps giving me an error.
Solution
Program is Done :
Please try to Comment few lines when you want to see each Outputs
i.e Output-1, Output-2, Output-3 and Output-4
Bowler.java
