关于golang:console打印动态进度条

type Reader struct {
    io.Reader
    Total   int64
    Written int64
}

func (r *Reader) Read(b []byte) (n int, err error) {
    n, err = r.Reader.Read(b)

    r.Written += int64(n)
    fmt.Printf("\r进度 %.2f%%", float64(r.Written*10000/r.Total)/100)

    return
}

            for (int i = 1; i <= 100; i++) {
                try {
                    TimeUnit.SECONDS.sleep(1);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                System.out.print("\r我的进度是" + i + "%");
            }
