java - File created but returns false -


i don't understand why don't enter in second if. first check if file exists (no, logic), create it, , check again still returns false. tried hour find problem , i'm sure it's stupid error. sorry poor english

here code:

package com.example.testcreatefileonclick;  import java.io.file; import java.io.fileoutputstream; import java.io.outputstreamwriter; import android.app.activity; import android.os.bundle; import android.view.view; import android.view.view.onclicklistener; import android.widget.button;  public class main extends activity implements android.view.view.onclicklistener{      button button;     button addteam;     boolean append = true;      string name = "nomfichier.txt";      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);          button = (button)findviewbyid(r.id.button1);         button.setonclicklistener((onclicklistener) this);         addteam = (button)findviewbyid(r.id.button2);         addteam.setonclicklistener((onclicklistener) this);      }      @override     public void onclick(view v) {         try {             file fichier = new file(name);               if (!fichier.exists()) {                 system.out.println("file doesn't exists");             }               fileoutputstream fout = openfileoutput(name, mode_world_readable);             outputstreamwriter osw = new outputstreamwriter(fout);              osw.write("text");             osw.flush();             osw.close();              //why don't go in if ?             if (fichier.exists()) {                 system.out.println("file exists");             }           } catch (exception e) {             // todo: handle exception         }     } }

edit: working code

package com.example.testcreatefileonclick;  import java.io.file; import java.io.filewriter; import java.io.ioexception;  import android.app.activity; import android.os.bundle; import android.view.view; import android.view.view.onclicklistener; import android.widget.button;  public class main extends activity implements android.view.view.onclicklistener{      button button;     button addteam;     boolean append = true;     string name = "nomfichier.txt";      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);          button = (button)findviewbyid(r.id.button1);         button.setonclicklistener((onclicklistener) this);         addteam = (button)findviewbyid(r.id.button2);         addteam.setonclicklistener((onclicklistener) this);      }      @override     public void onclick(view v) {         try {             string filepath = (this.getfilesdir().getpath().tostring());             file fichier = new file(filepath + name);              if (!fichier.exists()) {                 system.out.println("file doesn't exists");             }              fichier.createnewfile();             filewriter file = new filewriter(filepath + name);             file.write("text");             file.flush();             file.close();              if (fichier.exists()) {                 system.out.println("file exists");             }           } catch (ioexception e) {             system.out.println("exception");             e.printstacktrace();         }     } }

try replacing :

fileoutputstream fout = openfileoutput(name, mode_world_readable);         outputstreamwriter osw = new outputstreamwriter(fout);          osw.write("text");         osw.flush();         osw.close();

by :

fichier.createnewfile(); filewriter file = new filewriter(name); file.write("text"); file.flush(); file.close();

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
