java - handling of different delimiters of a csv file -


i new java , know basics now. have csv file lines of following structure:

int,,text,text,int,text,text,text,,text,text,,text,text,,,text,,text,,,int,int

i confused when saw csv file since separated single commas, double commas , triple commas. specific text or int empty , excel can´t handle display csv in correct way more.

so thought use java write program make columns separated 1 comma. , save result in new csv file afterwards. (i haven´t implemented how write in file) research managed write file reader read csv file that´s it. how can come desired result?

what have done far: 

import java.io.bufferedreader; import java.io.filereader; import java.io.ioexception; import java.util.arraylist; import java.util.arrays;  class read {     public static void main(string[] args) {          filereader myfile = null;         bufferedreader buff = null;         final arraylist<string> lines = new arraylist<string>();          try {             myfile = new filereader("thisisthepathofthecsvsource");             buff = new bufferedreader(myfile);             string line;             while ((line = buff.readline()) != null) {                  lines.add(line);              }         } catch (ioexception e) {             system.err.println("error2 :" + e);         } {             try {                 buff.close();                 myfile.close();             } catch (ioexception e) {                 system.err.println("error2 :" + e);             }         }          final string[][] valuesarray = new string[lines.size()][];         int cnt = 0;         (final string line : lines) {             valuesarray[cnt++] = line.split(",");         }          (string[] arr : valuesarray) {              system.out.println(arrays.tostring(arr));         }     }  }

try open source library univocity-parsers, provides solution of columns separator following:

csvparsersettings settings = new csvparsersettings(); settings.setskipemptylines(true); settings.getformat().setlineseparator("\n"); settings.getformat().setquote(',');        settings.getformat().setquoteescape('\\');  // escape double backslash

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
