本文介绍了一个使用Java实现的随机行走模拟程序。该程序通过用户输入步数，模拟一个随机行走过程，并记录并显示每一步的位置及最大位置。此模拟有助于理解随机过程的特性。

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
