[SOLVED] Read From LOGFILE

[Mir]

So what can i do for this....

[Eranga]

Ok, easy way to solve this is, change the log file with a space between number and string. Like this,

192.158.5.9 kjnkjnkn
192.158.5.9 kasasdas
192.158.5.9 asdsad
192.158.5.9 sadasdsad
192.158.5.9 sadsad
192.158.5.9 rtertre
192.158.5.9 rtret
192.158.5.9 cbvv
192.158.5.9 cvbnghh
192.158.5.9 fghfgn
192.158.5.9 tyty

Or you have to edit the code, to handle all spaces. But it's not easy.

I'm worried how it happened if it's a log file. Log file should have quite same pattern. In your file I found tab spaces, character spaces an mix of them too.

The above file format works perfectly on my code.

[Mir]

it is working for spaces,but my log file i have use Tab ,so how can i do for tab.
Plz help me

[Eranga]

Change the split regex to tab space.

    private void doProcessing(String strr) {
        String newStr = strr.split("\t")[0];
        removeDuplicates(newStr);
    }

[Mir]

thxs it is working for tab..

[Mir]

can i count how many time 192.158.5.9 is present in log file..

[Eranga]

You want to find only the 192.158.5.9 number of occurrence. Don't you have any other IPs.

[Mir]

All occurrence IPs

[Eranga]

You have to maintain counters for each. Update in each time you find a such IPs.

[Mir]

Thxs for solution..

[Eranga]

Did you get to work now?

[Mir]

yes..But i have a problem to impliment your code in my main code..Can you help me for impliment.

If yes then i post code formate..

[Eranga]

Oki, I'll help you. Why, is that much complicated?

[Mir]

ok

My Code formate is..In this .java file no Main class..

From where you start to read line-by-line of the log file.

[Mir]

From here...

FileReader fr = new FileReader("./" +str3);
BufferedReader br = new BufferedReader(fr);

[Eranga]

From here...

[COLOR="DarkGreen"]FileReader fr = new FileReader("./" +str3);
BufferedReader br = new BufferedReader(fr);
[/COLOR]

Replace the above code with this.

        FileReader fr = null;
        str = new ArrayList<String>();
        try {
            fr = new FileReader("./" +str3);
            BufferedReader br = new BufferedReader(fr);
            
            String temp;
            
            while((temp = br.readLine()) != null) {
                doProcessing(temp);
            }
            printResult();
        } 
        catch (IOException ex) {
            Logger.getLogger(Completed.class.getName()).log(Level.SEVERE, null, ex);
        }        
        finally {
            try {
                fr.close();
            } catch (IOException ex) {
                Logger.getLogger(Completed.class.getName()).log(Level.SEVERE, null, ex);
            }
        }

[Mir]

just i check it

[Eranga]

Define the array list in class level, just after the class declaration. As follows,

private ArrayList<String> str;

[Mir]

Here some error :--
After add
private ArrayList<String> str;

   doProcessing(temp);
printResult();
Logger.getLogger(Completed.class.getName()).log(Level.SEVERE, null, ex);
Logger.getLogger(Completed.class.getName()).log(Level.SEVERE, null, ex);

In these error showing...
