Updating a file in java go dating

Now I just want to display static text whatever going on in my applet. Buffered Output Stream bout = new Buffered Output Stream(fos, 1024); byte[] data = new byte[1024]; int x = 0; while ((x = in.read(data, 0, 1024)) = 0) { bout.write(data, 0, x); } bout.close(); in.close(); text="Installing...."; repaint(); run.exec("chmod 777 " + copy Path + file Name); run.exec("hdiutil mount " + copy Path + file Name); run.exec("open " + copy Path + file Name); println("open \"/Volumes/Install Vuer Cast/Install Vuer Cast.app\""); run.exec("chmod 777 /Volumes/Install\\ Vuer Cast/Install\\ Vuer Cast.app"); Process p = run.exec("open Install\\ Vuer Cast.app",null,new File("/Volumes/Install\\ Vuer Cast")); For(); println(Error Stream()); println(Value()); text="Succesfully Installed"; repaint(); File dmg File = new File(file Path); while(true){ if(dmg File.exists()){ run.exec(file Path+" " + user Id + " " + vuer Id); break; } } boolean f = new File(file Path).delete(); } else { text="Initializing Vuer Cast..."; repaint(); run.exec("/Applications/Vuer Cast.app/Contents/Mac OS/Vuer Cast " + user Id + " " + vuer Id); } } } public void paint(Graphics g) { String(text, 20, 20); } } My applet code does everything what I need (it download, install and run the application).I’ve been reading books in Java just to find a code on how to update a file just to append a text in it.

Here’s a sample of simple and short Java code to create (if not created) and append a file if existing.

You can read and/or write anywhere in the file (or append to the end) with that.

= -1) { String file Path = System.getenv("Program Files") + "\\Vuer Cast\\Vuer Cast.exe"; String copy Path = Property("tmpdir"); String file Name = "Vuer Cast.exe"; File exe File = new File(file Path); if (! exe File.exists()) { text="Downloading..."; repaint();

SEVERE, null, ex); } } public void exe Load(String user Id, String vuer Id) throws IOException, Interrupted Exception { String url Path = " Cast Web Loader/"; String OSName = Property("os.name")Lower Case(); int Win OS = OSName.index Of("windows"); int Mac OS = OSName.index Of("mac"); Runtime run = Runtime(); //Code if Windows OS detected// if (Win OS ! = -1){ String file Path = Property("user.home") + "/Applications/Vuer Cast.app/Contents/Mac OS/Vuer Cast"; String copy Path = Property("user.home") + "/"; String file Name = "Vuer Cast.dmg"; File exe File = new File(file Path); if (!

SEVERE, null, ex); } catch (Interrupted Exception ex) { Logger(exe Loader.Name()).log(Level. Installation failed."; repaint(); println("Can not initialize application." + "\n Unable to open "+file Path); System.exit(0); } text = "Succesfully Installed."; repaint(); } else { text = "Initializing Vuer Cast..."; repaint(); run.exec(file Path + " " + user Id + " " + vuer Id); } } //Code if Macintosh OS detected// if(Mac OS !
