java报错出现未知源,java.io.FileInputStream.(未知来源)

您好在eclipse中部署了以下代码

//import cs1.Keyboard;

import java.util.*;

import java.io.*;

public class Parser

{

public static void main (String[] args) throws IOException

{

String [][] addyArray = new String[50][4];

for (int j=0; j<50; j++)

{

for (int k=0; k<4; k++)

{

addyArray[j][k] = "

}

FileReader inFile = new FileReader ("sample.txt");

BufferedReader in = new BufferedReader (inFile);

String line = "";

int i = 0, a = 0;

while(in.ready())

{

line = in.readLine();

while (line != null && line != "

{

addyArray[i][a] = line;

line = in.readLine();

a++;

if (line == null) line = "

}

i++;

a = 0;

}

for(int j=0; j<3; j++)

{

for(int k=0;k<4;k++)

{

System.out.println((j+1) + "-" + (k+1) + " " + addyArray[j] [k]);

}

我在此行得到以下错误FileReader inFile = new FileReader(“ sample.txt”);

at java.io.FileInputStream.(Unknown Source)

at java.io.FileReader.(Unknown Source)

at Parser.main(Parser.java:19)

我将sample.txt文件放在了上面的源代码文件所在的包文件夹中.我不确定为什么会收到此错误.你能帮我一下吗.谢谢
