在Eclipse中读取Java中的.txt文件

Question

I am trying to read a file from my computer but it says java.io.FileNotFoundException (The system cannot find the file specified)

System.out.println("READING FILE"); 


    File file = new File("Testing.txt"); //Reading file from E
    FileInputStream in = null;
    BufferedInputStream buff = null;
    DataInputStream data= null;

    String Line=""; // declare a string 
    try
    {

        in = new FileInputStream(file); // pick up the file

        buff = new BufferedInputStream(in);
        data = new DataInputStream(buff);

        while (data.available() != 0) 
        { // Read the file line by line till it reaches the end of file

            Line=Line+data; // concatenate line into string

            System.out.println(data.readLine()); // print line by line 
        }

    } catch (IOException e)

    {
        e.printStackTrace();
    }

Answer 1

File file = new File("E:\\Testing.txt"); 

如果您尝试访问E，则这是实现此目的的方法之一

Answer 2

if you use windows try:

File file = new File("e:/Testing.txt");

(that means: use slash / instead of backslash \\ )

Answer 3

You need to either:

• Specify the complete path to the file, or...
• Set the app's default run directory in the project's run settings, or...
• Put the file on the classpath and read it as a resource

Answer 4

Where is the path of Testing.txt ???

File file = new File("Testing.txt"); //Reading file from E

Here java You are reading from out of src path if the file is in src you should modify the path

File file = new File("src/Testing.txt"); //Reading file from E

And another solution is enter the full path of file

Answer 5

指定文件的完整路径即可。

Answer 6

给出完整路径而不是相对路径
