Question

我有以下代码：

import.java.io.*;
public class BasheminParkingLot
{
    public static void main(String[]args)throws Exception
    {
        Stack parkinglot = new Stack();
        Stack alley= new Stack();
        File f = new File("bashemin.in");
        FileInputStream finstream = new FileInputStream(f);
        InputStreamReader finreader = new InputStreamReader(finstream);
        BufferReader finput = new BufferReader(finreader);
        String line = finput.readLine();
        String plate = "";
        System.out.println();
        System.out.println("The Bashemin Status");
        System.out.println();

        while(line!=null)
        {
            if(line.charAt(0)=='a')
            {
                plate = line.substring(1);
                System.out.println ("car" + plate + " arrived and parked");
                parkinglot.Push(plate);
            }
        }

    }
}

我收到了错误：

BasheminParkingLot.java:13：错误：找不到符号 BufferReader finput = new BufferReader（finreader）; ^

我想知道是否有人可以帮我调试这个？谢谢！

这不应该是BufferReader。它应该是BufferedReader。

以下代码可以使用：

import java.io.*;

class Stack {
    int x;

    void Push(String value) {
        // DO SOMETHING
    }
}

public class BasheminParkingLot
{
    public static void main(String[]args)throws IOException
    {
        Stack parkinglot = new Stack();
        Stack alley= new Stack();
        File f = new File("bashemin.in");
        FileInputStream finstream = new FileInputStream(f);
        InputStreamReader finreader = new InputStreamReader(finstream);
        BufferedReader finput = new BufferedReader(finreader);
        String line = finput.readLine();
        String plate = "";
        System.out.println();
        System.out.println("The Bashemin Status");
        System.out.println();

        while(line!=null)
        {
            if(line.charAt(0)=='a')
            {
                plate = line.substring(1);
                System.out.println ("car" + plate + " arrived and parked");
                parkinglot.Push(plate);
            }
        }

    }
}

错误：无法找到BufferReader的符号
