Processing a string of information

I have a text file that holds baseball teams as YEAR:TEAM1:POINTS1:TEAM2:POINTS2 on each line.

How can I process it so that I wind up with the year, 1st team's name, and if they won or not?

I know I should use delimiter \n and : to separate the data, but how can I actually keep track of the info that I need?

Here is an example found at java-examples.com

String str = "one-two-three";
  String[] temp;

  /* delimiter */
  String delimiter = "-";
  /* given string will be split by the argument delimiter provided. */
  temp = str.split(delimiter);
  /* print substrings */
  for(int i =0; i < temp.length ; i++)
    System.out.println(temp[i]);//prints one two three on different lines

Now for reading the input you can use BufferedReader and FileReader check examples for that on google.

try something like this

public static void readTeams() throws IOException{
    try {
        fstream = new FileInputStream("yourPath");
        in = new DataInputStream(fstream);
        br = new BufferedReader(new InputStreamReader(in));
        String s = br.readLine();
        String[] tokens = s.split(":");
        while(s!=null){               
        for (String t : tokens){
            System.out.println(t);
            }
        }
        in.close();
    } catch (FileNotFoundException ex) {    
        Logger.getLogger(YourClass.class.getName()).log(Level.SEVERE, null, ex);
    }
}

How about a healthy serving of Regex?

Have a look at the String class's split method.

To split the text you can use the methods String#indexOf(), String#lastIndexOf() and String#subString.

Then to compare which team has one, I would convert the String into an int and then compare the two values.

Since this is homework, here is not the solution, but just some hints:

  • Have a look at the class StringTokenizer to split the line.
  • Have a look at InputStreamReader and FileInputStream to read the file.
