Please clarify your problem. Which type of program you want to create in java? Please specify this.

A company has a file with records of employees name and team number. Each team has 5 members. The 3rd member of each team is the team leader. Write a program to read the records from this file and display the names of the teamleaders on the screen

We have took 2 teams with 5 members each. Depend of which we have created the following code:

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

public class TeamLeader{
    public static void main(String []args) throws Exception{
    FileInputStream fstream = new FileInputStream("leader.txt");
    DataInputStream in = new DataInputStream(fstream);
    BufferedReader br = new BufferedReader(new InputStreamReader(in));
    String strLine;
    ArrayList list=new ArrayList();
    while((strLine = br.readLine()) != null){
    list.add(strLine);
    }
    String team1[]=new String[5];
    String team2[]=new String[5];
    Iterator itr;
    int k=0,p=0;
    for (itr=list.iterator(); itr.hasNext(); ){
    String str=itr.next().toString();  
    String [] splitSt =str.split(" ");
    String name="",num="";
      for (int i = 0 ; i < splitSt.length ; i++) {
      name=splitSt[0];
      num=splitSt[1];
          }
          if(Integer.parseInt(num)==1){
          team1[k]=name;
          k++;
          }
          if(Integer.parseInt(num)==2){
          team2[p]=name;
          p++;
          }
    }
    System.out.println("Team Leader of Team 1: "+team1[2]);
    System.out.println("Team Leader of Team 2: "+team2[2]);

    }
}
