For this program, we need to read in a file which has baseball stats. Our program reads in the dat file then parses each line in the file. The file looks like this:

Joe h,o,h,s,h,o,h,h,h,o,o,o
Bill s,o,o,h,h,o,s,s,o

So far I'm ok with this. Here is the part that I'm struggling with. We have to modify the inner loop that parses a line in the file to count (seperately) the number of h, o, and s in each line.

Any help would be appreciated.

Here is my java program so far.

import java.util.Scanner;
import java.io.*;


public class BaseballStats
{
//-------------------------------------------------
//  Reads baseball stats from a file and counts
//  total hits, outs, walks, and sacrifice flies
//  for each player.
//-------------------------------------------------
public static void main (String[] args) throws IOException
{
Scanner fileScan, lineScan;
String fileName;


Scanner scan = new Scanner(System.in);


System.out.print ("Enter the name of the input file: ");
fileName = scan.nextLine();
fileScan = new Scanner(new File("stats.dat"));


// Read and process each line of the file


while (fileScan.hasNext())
{
fileName=fileScan.nextLine();


lineScan = new Scanner (fileName);
lineScan.useDelimiter(",");
while (lineScan.hasNext())
lineScan.next();
System.out.println();



}
}
}

I'm thinking this is how you would do it: Have three counter variables:

sCount
oCount
hCount

String input = file.readLine();

for (int i=0; i<input.length(); i++)
{
  if (input.charAt(i) == "s")
  {
         sCount++;
  }
  else if (input.charAt(i) == "o")
  {
        oCount++;
  }
  else if(input.charAt(i) == "h")
  {
        hCount++;
  }
}

Of course that String is after you deal with parsing the name of the player
Don't know if that will help

ok, good so far but how do I parse the names for the players?

This is where I am now:

import java.util.Scanner;
import java.io.*;


public class BaseballStats
{
//-------------------------------------------------
//  Reads baseball stats from a file and counts
//  total hits, outs, walks, and sacrifice flies
//  for each player.
//-------------------------------------------------
public static void main (String[] args) throws IOException
{
Scanner fileScan, lineScan;
String fileName;
int oCount=0, hCount=0, sCount=0, wCount=0;
Scanner scan = new Scanner(System.in);


System.out.print ("Enter the name of the input file: ");
fileName = scan.nextLine();
fileScan = new Scanner(new File("stats.dat"));


// Read and process each line of the file


while (fileScan.hasNext())
{
fileName=fileScan.nextLine();
//System.out.println (" " +fileName);


lineScan = new Scanner (fileName);
lineScan.useDelimiter(",");


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


{
if (fileName.charAt(i) == 's')
{
sCount++;


}
else if (fileName.charAt(i) == 'o')
{
oCount++;


}
else if(fileName.charAt(i) == 'h')
{
hCount++;


}
else if (fileName.charAt(i) == 'w')
{
wCount++;


}


}


System.out.println(lineScan.next()+"  Walks: "+wCount+"  Hits: "+hCount+"   Sacrifice: "+sCount+"  Outs: "+oCount);


}
}
}

It takes a running count of all stats but I only want stats per player...how do I do that?

Here is the text file I'm reading from:

Willy Wonk,o,o,h,o,o,o,o,h,w,o,o,o,o,s,h,o,h
Shari Jones,h,o,o,s,s,h,o,o,o,h,o,o,o,o
Barry Bands,h,h,w,o,o,o,w,h,o,o,h,h,o,o,w,w,w,h,o,o
Sally Slugger,o,h,h,o,o,h,h,w
Missy Lots,o,o,s,o,o,w,o,o,o
Joe Jones,o,h,o,o,o,o,h,h,o,o,o,o,w,o,o,o,h,o,h,h
Larry Loop,w,s,o,o,o,h,o,o,h,s,o,o,o,h,h
Sarah Swift,o,o,o,o,h,h,w,o,o,o
Bill Bird,h,o,h,o,h,w,o,o,o,h,s,s,h,o,o,o,o,o,o
Don Daring,o,o,h,h,o,o,h,o,h,o,o,o,o,o,o,h
Jill Jet,o,s,s,h,o,o,h,h,o,o,o,h,o,h,w,o,o,h,h,o

You could use the firstIndexOf() method to return the occurence of the first ","...That method will return an int value, and once you have that, then you can create a substring with just the name, and that will also make it to were you can create a substring of everything to the right, and use the code I gave you in the first post.

String input = file.readLine();
int point = input.firstIndexOf(",");

String name = input.substring(0,point);
String records = input.substring(point,input.length());

That's something what it will look like.

Hmm...You would have to read one line at a time, and once finished with the calculations, you would have to reset the variables.
