java - Buffer string to array list, and split -


i buffering text file of 'arraylist lines' need split each line new arraylist parts, can find information each line , add data model have built, reason using arraylists because of there expandable properties, meaning wont need worry size of either line or text file.

the code below:

    try(bufferedreader buffer =              new bufferedreader(new filereader("src/sample.txt")))     {         string currentline;         arraylist<string> lines = new arraylist<string>();         arraylist<string> parts = new arraylist<string>();         //listiterator<string> lineitr = lines.listiterator();          while((currentline = buffer.readline()) != null)         {             lines.add(currentline);              for(string line : lines)             {                 parts.addall(line.split("\\s+"));              }               //lineitr.next();             //lineitr.set(currentline);              //system.out.println(lineitr.next());         }     }     catch(ioexception e)     {         e.printstacktrace();     }  }

i having troubles parts.addall(line.split("\s+"); not understand why statement not iterate through lines, splitting , adding each part of string parts array list, misunderstanding here?

thanks babble

string.split() returns array of string . have use arrays.aslist() convert list .

parts.addall(line.split("\\s+"));

above line should be:

parts.addall(arrays.aslist(line.split("\\s+")));

or :

collections.addall(parts, line.split("\\s+"));

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
