Question

I’m trying to read a file in eclipse and print it. The problem is that the compiler always says to me that the file or directory doesn’t exist. I have to use relative paths.

The relevant part of the project routes is:

• uva.pfc.refactoringEngine.core <–Project
  • …
  • src
    • uva.pfc.refactoringengine.core.actions <– Actual Package
      • …
      • CreateEnumSetPlusClas.java <–File from I want to read the EnumSetPlus.java file
    • …
    • EnumSetPlus.java <– File I want read and print

This is the code:

String total="";

File actual = new File("src/EnumSetPlus.java"); 

FileReader filereader = null; 

try { 
filereader = new FileReader(actual); 
} 
catch (FileNotFoundException e) { 
// TODO Auto-generated catch block e.printStackTrace(); 
} 

BufferedReader input = new BufferedReader(filereader); 

try { 
while ((line = input.readLine()) != null) 
{ 
total += line + "\n"; 
} 
input.close(); 
} 
catch (IOException e) {
// TODO Auto-generated catch block e.printStackTrace(); 
} 

System.out.println(total);

I think the problem is that I have to do something if I want the file path recognised by de eclipse project.

Could you help me??

Thaks beforehand.

I’d use getClass().getResourceAsStream("/EnumSetPlus.txt") – this will look for the file on the root of the classpath (which is bin/, but all files from src go to bin). You then get an InputStream which you can adapt to Redaer via new InputStreamReader(stream, encoding)
