JAVA 若何在LINUX COPY files時出現PROCESS圖標－桃園網頁設計

有利用過進度條的伴侶必然會感覺很不便利
因為要從0~100讀取鋪張時候
因檔案巨細也不知道這時候間讀寫的完嗎？
如這篇
Java Swing 若何使用進度

於是經由批改
改成此方式
可使用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();
