Hi Friend,

Here is the studentRecord.txt:

1 A 90 PASS
2 B 30 FAIL
3 C 80 PASS
4 D 99 PASS
5 E 85 PASS
6 F 25 FAIL

Try the following code:

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

public class SearchWord{
public static void main(String[]args) throws Exception{
Scanner input=new Scanner(System.in);
System.out.print("Enter word to find: ");
String word=input.next();
if(word.equals("FAIL")){
File f = new File("studentRecord.txt");
BufferedReader freader = new BufferedReader(new FileReader(f));
String s;
while ((s = freader.readLine()) != null) {

String[] st = s.split(" ");
String id = st[0];
String name = st[1];
String marks = st[2];
String result = st[3];
if (result.equals(word)) {
File file = new File("result.txt");

FileWriter fstream = new FileWriter(file,true);
BufferedWriter out = new BufferedWriter(fstream);
out.write(id+" "+name+" "+marks);
out.newLine();
out.close();
}
}
}
}
}

Hope that it will be helpful for you.
Thanks
