我正在为我的课程开发一个项目,我们应该读一个名为sampleSearch.txt的文件,其中包含我正在使用的代码。问题是通过eclipse我似乎无法真正加载文件。即使文本文件与其余代码位于同一目录中,它总是会出现File Not Found。
import java.util.*;
import java.io.*;
public class Driver{
public static void main (String[] args){
// try block needed to read in file
try
{
//open the file "sampleSearch.txt"
FileReader fileName = new FileReader("sampleSearch.txt");
Scanner fileRead = new Scanner(fileName);
//read in the number of rows
int numRow = fileRead.nextInt();
fileRead.nextLine();
//read in the number of columns
int numCol = fileRead.nextInt();
fileRead.nextLine();
//create a 2d array to hold the characters in the file
char[][] array = new char[numRow][numCol];
//for each row in the file
for (int r = 0; r < numRow; r++)
{
//read in the row as a string
String row = fileRead.nextLine();
//parse the string into a sequence of characters
for (int c = 0; c < numCol; c++)
{
//store each character in the 2d array
array[r][c] = row.charAt(c);
}
}
//create a new instance of the WordSearch class
WordSearch ws = new WordSearch(array);
//play the game
ws.play();
}
catch (FileNotFoundException exception)
{
//error is thrown if file cannot be found. See directions or email me...
System.out.println("File Not Found gribble");
}
}
}
答案 0 :(得分:13)
您需要知道代码在哪个目录中搜索文件:
这样做:
获取当前路径:System.out.println(new File(".").getAbsoluteFile());
这将显示java代码查找文件的路径。使用从此位置开始的相对路径引用您的文件。干杯
