Searching File for a given String using Command-line arg.

[emcee]

I'm to create a program that reads files through the command-line
using a for loop to process each of the file
(ie. search for string "out" in given files)
using scanner methods such as hasNextline() and nextLine etc.

the only thing i am having trouble with is the for loop.
how would i do this?

thanks in advance.

What is that command line supposed to contain? The names of the files to test?

yes..

import java.util.Scanner;
import java.io.*;
class Parse
{
public static void main(String args[])
{
try{
Scanner sc = new Scanner(new File(args[0]));
int count = 0;
while(sc.hasNext())
{
String result = (String)sc.next();
if(result.contains("for")){
count = count+1;
}
}
System.out.println(count);
}catch(Exception e){
e.printStackTrace();
}
}
}


where args[0] is here Filename..

You should loop through all the file names args[i] and process them. btw what do
you do with 'words' such as "forkformforum" when you search for the word "for"?

Hi,
Thank u for correcting my code..
I have altered n now it works fine..

import java.util.Scanner;
import java.io.*;
class Parse{
public static void main(String args[]){
try{
Scanner sc = new Scanner(new File(args[0]));
int count = 0;
while(sc.hasNext()){
String result = (String)sc.next();
if(result.contains("for")){
for(int i=0;i<result.length();){
int j = i+3;
if(j<=result.length()){
if("for".equals(result.substring(i,i+3)))
count++;
}
i=i+3;
}
}
}
System.out.println("count:::::::::"+count);
}catch(Exception e){
e.printStackTrace();
}
}
}
