help with formatting output while reading a file

[john89011]

Hi guys,

I am trying to read a text file and format the output a certain way. This is what I have so far and all it does it outputs the entire text file, I can't figure out how to have it print line by line, do the calculation and format the text, I looked at formatter but it would just print everything on a single line... any input would be greatly appreciated!

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Formatter;
import java.util.Scanner;

public class ScannerReadFile {

public static void main(String[] args) {
String name, major;

File file = new File("C:\\Users\\pericjo\\workspace\\john\\src\\da ta.txt");
try {
Scanner scn = new Scanner(file);
while (scn.hasNextLine()) {
String line = scn.nextLine();
System.out.println(line);
}
} catch (FileNotFoundException e) {
}
}
}


Here's the text file content:

John Smith
CS
89
99
Jonathan Sou
MATH
78
98
College
CS
78
87
Math Dept
MATH
99
66
Comp Science
CS
88
100


And the output should look like:


John Smith, CS, 89.0, 99.0
Jonathan Sou, MATH, 78.0, 98.0
College, CS, 78.0, 87.0
Math Dept, MATH, 99.0, 66.0
Comp Science, CS, 88.0, 100.0
----- ---------- ----------
MATH Math AVG= 88.5 Java AVG= 82.0
CS Math AVG= 85.0 Java AVG= 95.33333333333333

Thanks!

Write a format that matches one of those lines.
Feed it the correct values in a loop (possibly even create an object representing that data).
