Re: tab separated file

That depends what "second section" means. If you can't be more specific than that, you have little chance of getting a program to do something with it.

Re: tab separated file

Then use String.split() to separate it and read the second element of the result.

Re: tab separated file

array is an arraylist<string>

Java Syntax (Toggle Plain Text)
  1.  for (int i = 0; i<array.size(); i++)
  2.         {
  3.             System.out.println(array.get(i).split(" "));
  4.  
  5.         }

i get: [Ljava.lang.String;@ca0b6

i am supposed to get "10.0.0.2"

Re: tab separated file

Really? Because this particular part would seem to be clearly saying something else
Quote ...
Returns:
the array of strings computed by splitting this string around matches of the given regular expression
Notice the array part.

(Also, there does not appear to be anyone named "u" here at the moment. Use proper English.)

Re: tab separated file

It splits on a particular expression, which in your case should be tab, and returns an array of the pieces. If you want the second section then you just need the second element of that array.
