Explanation / Answer

Hi ,

Please see below the class:

RankReader.java

import java.io.BufferedReader;

import java.io.FileReader;

import java.io.IOException;

public class RankReader {

/**

* @param args

public static void main(String[] args) {

//Reading the content of a file named "RankList.txt"

BufferedReader br = null;

FileReader fr = null;

int lineCount =0;

String fileContent = "";

try {

fr = new FileReader("RankList.txt");

br = new BufferedReader(fr);

String sCurrentLine;

while ((sCurrentLine = br.readLine()) != null) {

if(lineCount !=0){

String [] lineArr = sCurrentLine.split(" ");

//Printing Year

System.out.println("Ramk list for "+lineArr[0]);

//Prining Girl's Rank list

System.out.println("Girl's Ranklist");

for(int i=1;i<=5;i++){

System.out.println("Rank "+i+" : "+lineArr[i]);

}

//Printing Boys's Rank list

System.out.println("Boy's Ranklist");

for(int i=6,j=1;i<=10;i++,j++){

System.out.println("Rank "+j+" : "+lineArr[i]);

}

lineCount++;

}

} catch (IOException e) {

System.out.println("Invalid File!");

}
