Splitting a line to objects in java

Question

I am reading a file. I need to convert each value to java object.

String sCurrentLine;
BufferedReader br = null;
int pointer = 1;
try {
    br = new BufferedReader(new FileReader("src/main/java/com/ali/trillium/p0f.log"));
} catch (FileNotFoundException e) {
    e.printStackTrace();
}
while ((sCurrentLine = br.readLine()) != null) {
    System.out.println(sCurrentLine);
    System.out.println("---------------");
    System.out.println(pointer++);
    System.out.println("---------------");
}

Output of program

<Tue Apr 10 09:21:42 2018> 172.20.16.36:62385 - Windows XP/2000 (RFC1323+, w+, tstamp-) (ECN) [low cost] [GENERIC] Signature: [8192:113:1:52:M1352,N,W8,N,N,S:.:Windows:?] -> 172.20.16.23:3391 (distance 15, link: unknown-1392)

@KamranKhan you have a lot of good suggestions in the comments. Take every topic mentioned and read up on it. I get the feeling you should spend more time learning the language. Sit down and read stuff — Neuron, Apr 17 '18 at 12:32

Like Lonely Neuron suggested :

You should use delimiting libraries in order to parse your output into a working data structure. You can use the split function to achieve this:

s.split("delimiter"); // replace delimiter with the actual delimiting in the output

Please note that the parameter of split is a regex expression, so be cautious with passing things like ".". Assuming you have a multiple line output - you may want to use multiple calls to the split method.

There are numerous ways to perform delimiting in java: you can use a Scanner, or a StringTokenizer (second answer) as well.

Good Luck!
