Terminal Based Progress Bar for Java Applications

March 31st, 2019 by

Recently I needed to add a progress bar to a Java based terminal/console application and I used a specific library that I’d like to demonstrate in the following snippet.

Using Maven, we just need to add the following dependency:


Sample Application

The application shows how to set up the progress bar and how to advance its status by-one, by a given amount or to a specific number.

package com.hascode.tutorial;
import me.tongfei.progressbar.ProgressBar;
public class Sample {
  public static void main(String[] args) throws InterruptedException {
    try (ProgressBar pb = new ProgressBar("Downloading the internet", 2000)) {
      pb.stepBy(248); // step by n
      pb.stepTo(600); // step directly to n
      pb.setExtraMessage("Downloading..."); // Set extra message to display at the end of the bar
    System.out.println("we have downloaded the internet ...");

Running the Sample

We may now run the sample application e.g. by using Maven like this:

mvn clean compile exec:java -Dexec.mainClass=com.hascode.tutorial.Sample
Downloading the internet 100% │██████████████████████████████████████████████████████████│ 2500/2500 (0:00:04 / 0:00:00) Downloading...
we have downloaded the internet ...

Depending on the visual style configured the output might look similar to this one:
