推荐答案

我会建议你改变paint方法下一：

I would suggest you to change paint method to next:

 public void paint(Graphics graphics) {
    currentText = this.getText();
    if (currentChar < currentText.length()) {
        currentText = currentText.substring(currentChar);

    }
    graphics.drawText(currentText, 0, 0, DrawStyle.ELLIPSIS, 200);
}

所以不叫 super.paint（）在油漆。
