Code Explanation

final ProgressBarBuilder progressBarBuilder = new ProgressBarBuilder();

Constructs a new ProgressBarBuilder. You can view the documentation here.

You can reuse the builder, so you won't need to create a new ProgressBarBuilder every time you want to create a new progress bar.

---

progressBarBuilder.setPosition(10, 10);

This tells the builder to place the bar at position (10x, 10y).

---

progressBarBuilder.setWidth(20);

This sets the width of the bar to 20 cells.

---

panel.addComponents(progressBarBuilder.build());

This builds the bar and adds it to the panel.
