Hey guys,
First time poster here, although I've been trolling for a little while now. I'm in a Java 2 class and having trouble completing a practice program. It's supposed to search files that are given by the user at a command prompt for a specific word also given. Here is what I am working with for instructions
Write a program Find that searches all files specified on the command line and prints out all lines containing a keyword. For example, if you call
java Find Buff report.txt address.txt Homework.java
then the program might print the foll. (i.e., all the lines that contain the word "Buff"):
report.txt: Buffet style lunch will be available at the
address.txt: Buffet, Warren|11801 Trenton Court|Dallas|TX
address.txt: Walters, Winnie|59 Timothy Circle|Buffalo|MI
Homework.java: BufferedReader in;
Here is what I have so far.
import javax.swing.*;
import java.awt.*;
import java.awt.geom.*;
import java.util.*;
import java.awt.event.*;
import java.io.*;
//java Find Buff report.txt address.txt Homework.java
public class HW4c
{
public static void main(String[] args)
{
//String fileName1 = args[0];
String toFind;
try
{
Scanner input = new Scanner(System.in);
toFind = input.next();
String fileName1 = args[args.length - 1];
for( int i = 0; i < args.length; i++ ) //make ==
{
BufferedReader in = new BufferedReader( new FileReader( fileName1 ) );
String line = in.readLine();
while(line != null)
{
line = in.readLine();
if(line.indexOf(toFind, 1) == -1)
{
System.out.println(line);
}
}
}
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
Any help would be amazing!
