MIDP不支持小数。 所以画抛物线时只在模拟画了。 本代码就是模拟一个子弹飞行轨迹。-MIDP does not support the minority. So parabola painting only in a simulated painting. The simulation code is a bullet trajectories.

j2me中用查表法实现炮弹抛物线轨迹的例子,需要的朋友可以-j2me using look-up table to achieve the parabolic trajectory of the case shell, you need friends can see

j2me 小项目，一个可移动的小球，可留下轨迹-it is a j2me project ,a moving ball call leave guiji
