圖片顯示，螢屏上有兩張圖片，一張顯示正常圖片，一張顯示提示圖片。
回圈更換圖片，假定一次播放時間為80ms，
1.正常圖片與提示圖片同時顯示
2.正常圖片顯示80ms
3.提示圖片顯示前20ms，后60ms不顯示
下列代碼以顏色代替圖片，我該如何控制提示圖片，提示圖片顯示不穩定
import javax.swing.*;
import java.awt.*;
/**
* @className: JFrameTest
* @description: 正常圖片與提示圖片同時顯示，一次圖片更換時間 80ms，
* 正常圖片顯示80ms，提示圖片顯示前20ms，剩余60ms不顯示，
*
* @version: 1.0
