JAVA 如何在LINUX COPY files時泛起PROCESS圖標－苗栗水管清洗

有利用過進度條的朋友一定會感覺很不便利
因為要從0~100讀取虛耗時候
因檔案巨細也不知道這時候間讀寫的完嗎？
如這篇
Java Swing 如何利用進度

於是經由批改
改成此方式
可操縱DIALOG準確的抓到讀寫完成的時候

processdialog.setTitle("Copying files to USB");
processdialog.add(labelimg);
processdialog.setLocation(400,250);
processdialog.pack(); // Packs the dialog so that the JOptionPane can be seen
processdialog.setVisible(true); // Shows the dialog
new Thread(){
public void run(){
try{
Process process = null;
BufferedReader input = null;
final Runtime runtime = Runtime.getRuntime();
//extact tar for ext3 file
String tarstring = "tar -xvpf /"+tarpath+"/"+cellValue+".tar -C "+extpatition+"/";
process = runtime.exec(new String[]{"/bin/sh","-c",tarstring});
InputStream stdout = process.getInputStream ();
InputStreamReader osr = new InputStreamReader (stdout);
BufferedReader obr = new BufferedReader (osr);
process.waitFor();
Thread.sleep(2000);
}catch(Exception e){
e.printStackTrace();
}finally{
processdialog.dispose();
}
}
}.start();
