Java实现打印进度条

System.out.print("正在加载");
        for (int i = 0; i < 80; i++) {
            System.out.print(".");

            try {
                Thread.sleep(50);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        System.out.println();
        System.out.println("加载完成:100%");
