Show user that program still. Running

Question

I wrote a Java program that reads a file, process the numbers and then output result to to the user. The processing could take a while so I would like to display some sort of progress bar or just simply thinking glass (anything reallly) that indicate to the user that the program is actually processing something.

Any recommendation for quick Solution for it?

Thank you

Why don't you print a dot to stdout after every x records processed... — vikingsteve, Jun 30 '14 at 07:05
Quickest might be to use a [`ProgressMonitor`](http://docs.oracle.com/javase/7/docs/api/javax/swing/ProgressMonitor.html) — MadProgrammer, Jun 30 '14 at 07:06

When you say stdout, don't of mean system.out? If that's the case then it does not show any pop up window? — Snake, Jun 30 '14 at 15:10

Display a busy cursor:

try {
  component.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
  // process
} finally {
 component.setCursor(Cursor.getDefaultCursor());
}

Thank you but what would be the full code (i.e component)? Right now here is no gui or anything. – Snake Jun 30 '14 at 15:09

Command line progressbar

http://nakkaya.com/2009/11/08/command-line-progress-bar/

public static void printProgBar(int percent){
    StringBuilder bar = new StringBuilder("[");

    for(int i = 0; i < 50; i++){
        if( i < (percent/2)){
            bar.append("=");
        }else if( i == (percent/2)){
            bar.append(">");
        }else{
            bar.append(" ");
        }
    }

    bar.append("]   " + percent + "%     ");
    System.out.print("\r" + bar.toString());
}

Although this would answer the question, you should add some of the content from that link to your answer. Just in case the link gets unaccesible or someother thing. – Afzaal Ahmad Zeeshan Jun 30 '14 at 15:18
