io - Java text file remove doubles from four column text file -

i have write code take text file, contains integers , doubles, , print doubles in file , integers in one. text file formatted in following way:

double int int int   double int int int   ...   double int int int 

it saved in "raw.txt" file.

the output should like:

int int int   int int int    ...   int int int   

this have tried far:

import java.io.*; import java.util.*;  public class data {     public static void main(string[] args) throws filenotfoundexception {         printwriter writer = new printwriter(new file("sorted.txt"));         scanner reader = new scanner(new file("raw.txt"));         int temp = 0, count = 1;         while (reader.hasnext()) {             try {                 temp = reader.nextint();             }             catch (inputmismatchexception e) {                 reader.nextline();                 temp = (int) reader.nextdouble();             }             writer.print(temp);             if (count % 4 == 0)                  writer.println();              count++;              }         writer.close();         reader.close();     } } 

the current code throws inputmismatchexception. appreciated.

inputmismatchexception can thrown because nether integer either double
better read part string , decide
when deciding, throws numberformatexception can catched
in following code there 2 writers separated wanted, looks better code maybe
have corrected writing file. havent tested think if writer.print(temp);, put integers without spaces, useless then.
try code, not tested

import java.io.*; import java.util.*;  public class data {      public static void main(string[] args) throws filenotfoundexception {         printwriter writerint = new printwriter(new file("sortedint.txt"));         printwriter writerdou = new printwriter(new file("sorteddou.txt"));         scanner reader = new scanner(new file("raw.txt"));         int temp = 0, countint = 1, countdou = 1;         while (reader.hasnext()) {             string next = reader.next();             try{                 temp=integer.parseint(next);                 writerint.print(temp+" ");                 if (countint % 4 == 0)                      writerint.println();                  countint++;                 }catch(numberformatexception e){                 try{                     writerdou.print(double.parsedouble(next)+" ");                     if (countdou % 4 == 0)                          writerdou.println();                      countdou++;                    }catch(numberformatexception f){                     system.out.println("not number");                 }             }          }         writerint.close();         writerdou.close();         reader.close();     } }
