模拟n步一维随机游走的情况。
package randomWalk; import java.util.Random; import java.util.Scanner; public class RandomWalk { public static void main(String[] args) { Scanner console = new Scanner(System.in); System.out.print("intput the steps you want to walk:"); int steps =console.nextInt(); randomWalk(steps); } public static void randomWalk(int steps) { System.out.println("walking " + steps + " steps" ); Random r =new Random(); int position =0,max = position; int direction = 0; for(int i = 0;i< steps;i++) { direction = r.nextInt(2); if(direction == 1) position += 1; else position -= 1; if(position > max) max = position; System.out.println("position = " + position); } System.out.println("max postion = " + max); } }
结果类似于:
intput the steps you want to walk:7
walking 7 steps
position = 1
position = 0
position = -1
position = -2
position = -3
position = -2
position = -1
max postion = 1
