在命令提示符下运行 Java 时基于文本的加载栏？

public class TextProgressBar {
    private static final int PROGRESS_BAR_WIDTH = 50;

    public static void main(String[] args) throws InterruptedException {
        for (int i = 0; i <= 100; i++) {
            System.out.print("\r");
            System.out.print("[");
            for (int j = 0; j < PROGRESS_BAR_WIDTH; j++) {
                if (j < (i / 2)) {
                    System.out.print("=");
                } else {
                    System.out.print(" ");
                }
            }
            System.out.print("] " + i + "%");
            Thread.sleep(100);
        }
        System.out.println();
    }
}
