java五环编程代码 java环形数组

IT技术System

Java编程（写出程序代码）写了一个代码，代码如下，可以进行参考
public class sum {
public static void main(String[] args) {
//创建一个Scanner的对象input
Scanner input = new Scanner(System.in);
//提示用户输入数据
System.out.print("请输入一个整数");
//将输入的值赋给n
int n = input.nextInt();
//定义变量接收计算后的和
int sum = 0;
//利用循环进行求和
for (int i = 0; i = n; i) {
sum =i;
}
//输出最后的和
System.out.println("从0一直到" n "的所有整数的和是:" sum);
}
}
java怎么绘制五环图案？五环图片，其关键点是确定五个圆的中心点，只要确定了中心点，画圆就简单了，这个需要你计算了，可以先用笔在纸上画一画，想想思路，祝你成功
