Hello. I am having some trouble getting a java program to work. I am supposed to make a program that takes a word and a file name, and finds all lines in that file that contain that word.

The word that I chose was "try", and the file was "Sgrep.java"

Here is the main method:

Code:
class main {
public static void main(String[] args){
if(args.length != 2){
System.out.println("Usage: java Sgrep <string> <filename>");
return; }
Sgrep task = new Sgrep(args[0], args[1]);
}
}

and here is the class Sgrep:

Code:
import java.io.*;
public class Sgrep {
String find;
String file;
Sgrep(String fin, String fil)
{
find=fin;
file=fil;
}
public String getFilename() {
return file;
}
public String search() {
String currentLine;
if(find == null) {return "";}
try {
}
while(0==0) {
try {
} catch (IOException ex) {
}
}
}
}

I put a return statement after the FileNotFoundException that prints "File not found", and that is what I have been getting.

Did I do anything wrong that is not allowing the program to find the file? Because it is supposed to work.

I would appreciate any help,
Jeans

This is important, I need this done by this weekend.

EDIT: I got it to work. The assignment sheet had given an example output that showed the file name as Sgrep.java, however, in order to get the program to recognize the file, I had to type in the entire target (C:\Users\User\Sgrep\src\sgrep\Sgrep.java). That is two hours of my life I'll never see again .
