Junk characters while reading text file in java

Question

I have a java which calls windows bat file which does some processing and generates the output file. `Process p = Runtime.getRuntime().exec("cmd /c "+filename);` Now when reading the file from following program. (`filexists()` is function which checks whether file exists or not). Output file contains only single line ``` if ( filexists("output.txt") == true) { String FileLine; FileInputStream fstream = new FileInputStream("output.txt"); BufferedReader br = new BufferedReader(new InputStreamReader(fstream)); FileLine = br.readLine(); fstream.close(); filein.close(); } ``` Variable FileLine contains 3 junk charcters in the starting. I also checked few other files in the progam and no file has this issue except for the fact it is created with Runtime function. `ï»¿9087`. As you can see three junk characters are coming in the output file. When opened with Notepad++, i am not able to see those junk characters. Please suggest

Accepted Answer

This is happening because you have not mentioned the file encoding while creating your FileInputStream.Assuming your file is UTF-8 encoded, you need to do something like this

```
   new FileInputStream("output.txt, "UTF-8"));
```

Change the encoding as per the encoding of your file
