java 求弹球代码 需要排名 保存记录功能
真是不巧啊,居然做完了,或许我看到太晚了,呵呵,还是回答一下吧!
eclupse多线程,发射弹球遇边界弹回java编程
一,设置一个二维数组,数组的每一行代表一个球
二,小球移动的速度设置一个衰减因子,这样一定次数后会停止
三,小球的碰撞,小球速度改变
如何用Java绘图做出让小球在背景上运动的效果
java是编程语言里比较难学的一门,如果有心从事编程方向的工作,最好到专业机构学习并有更多的项目实践,更贴近市场,这样更有利于将来的发展。
java里弹球游戏怎么改变运动轨迹
通过控制线程的方式,改变弹珠在屏幕中的像素点,来做出移动的效果!
Java的自由落体题目问题?
具体的题目?我看提示没有按照要求判断弹球次数。而你是直接输入弹球次数,你求的是什么?
什么鬼提交后怎么变成。。。。
Scanner in = new Scanner(System.in);
int a = in.nextInt();
int qiu = 10000;
for (int i =1 ; i = a;i++)
{
qiu = qiu/2;
if (qiu == 0)
{
System.out.println("第" + i + "次反弹后,球体落地");
break;
}
}
if(qiu 0)
{
System.out.println(a + "次反弹后,当前球的高度是:" + qiu);
}
