Java: Updating text in the command-line without a new line

I'd like to add a progress indicator to a command-line Java program.

For example, if I'm using wget, it shows:

71% [===========================>           ] 358,756,352 51.2M/s  eta 3s

Is it possible to have a progress indicator that updates without adding a new line to the bottom?

Thanks.

I use following code:

public static void main(String[] args) {
    long total = 235;
    long startTime = System.currentTimeMillis();
    
    for (int i = 1; i <= total; i = i + 3) {
        try {
            Thread.sleep(50);
            printProgress(startTime, total, i);
        } catch (InterruptedException e) {
        }
    }
}


private static void printProgress(long startTime, long total, long current) {
    long eta = current == 0 ? 0 : 
        (total - current) * (System.currentTimeMillis() - startTime) / current;
    
    String etaHms = current == 0 ? "N/A" : 
            String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(eta),
                    TimeUnit.MILLISECONDS.toMinutes(eta) % TimeUnit.HOURS.toMinutes(1),
                    TimeUnit.MILLISECONDS.toSeconds(eta) % TimeUnit.MINUTES.toSeconds(1));
    
    StringBuilder string = new StringBuilder(140);   
    int percent = (int) (current * 100 / total);
    string
        .append('\r')
        .append(String.join("", Collections.nCopies(percent == 0 ? 2 : 2 - (int) (Math.log10(percent)), " ")))
        .append(String.format(" %d%% [", percent))
        .append(String.join("", Collections.nCopies(percent, "=")))
        .append('>')
        .append(String.join("", Collections.nCopies(100 - percent, " ")))
        .append(']')
        .append(String.join("", Collections.nCopies((int) (Math.log10(total)) - (int) (Math.log10(current)), " ")))
        .append(String.format(" %d/%d, ETA: %s", current, total, etaHms));
    
    System.out.print(string);
}

The result:

First when you write, don't use writeln(). Use write(). Second, you can use a "\r" to Carriage Return without using \n which is a New line. The carriage return should put you back at the beginning of the line.
