read text file into text area

[Robert Oliver]

I am trying to figure out how to read a text file and read it into a text area in my program. This should be fairly straight forward but I can't seem to get anything to work.
This doesn't work and I have tried several variations.

File filename = jfc.getSelectedFile();
try{// opens try
FileReader in = new FileReader(filename);
BufferedReader br =
new BufferedReader(in);
int c;
String s = br.read();
while ((c = in.read()) != -1)
br.write(c);
comments.append("\n" + s +"\n");
in.close();
br.close();
}// closes try

I'm not sure what you're doing here, but surely "br.write(c)" is wrong if br is a BufferedReader. The compiler should complain.

Enjoy, pass a string as the filepath, then get the contents of the file via getFileContent() which returns a stringbuffer. To create a string call
the toString() of the stringbuffer object. This code is really fast !!

public class FileReader
{
  private StringBuffer fileContent;
 
  public FileReader(String filePath)
  {
    try
    {
      int len = (int) (new File(filePath)).length();
 
      FileInputStream fis = new FileInputStream(filePath);
 
      byte buf[] = new byte[len];
 
      fis.read(buf);
 
      fis.close();
 
      fileContent = new StringBuffer(new String(buf, 0, len));
    }
    catch (FileNotFoundException e)
    {
      System.out.println("FileNotFoundException" + e);
    }
    catch (IOException e)
    {
      System.out.println("IOException" + e);
    }
  }
 
  /**
   * Gets the fileContent.
   * @return Returns a StringBuffer
   */
  public StringBuffer getFileContent()
  {
    return fileContent;
  }
}

Thanks Mark. Worked great. Simple and straight forward.
