publicstatic String message ="";
This is the error message I receive:
xchan.java:50: cannot find symbol
symbol : method append(java.lang.StringBuffer)
location:class java.lang.String
message = message.append(new StringBuffer()).append('\n').append(s1).toString();
What am I doing wrong here?

To where? I'm assuming you mean the parentheses around the "new StringBuffer" but they look correct to me.

I had already tried that, but I still get the same error message as before.
message is a String; it has no append() methods (has anyone mentioned to you that strings are immutable?). You should probably be declaring message as a StringBuffer instead of a String; then your append() calls will work as expected. For more specific help, we'll need to see the complete loop or method or whatever that statement is in.

message = s1.substring(s1.indexOf('"') + 1, s1.length());
if(s1.charAt(s1.length() - 1) != '"')
while((s1 = bufferedreader.readLine()) != null)
{
message = message.append(new StringBuffer()).append('\n').append(s1).toString();
if(s1.length() != 0 && s1.lastIndexOf('"') == s1.length() - 1)
break;
}
if(message.length() != 0)
message = message.substring(0, message.length() - 1);
Basically what it's doing is that s1 starts with message=" and then a block of text, which it is reading from a file. It turns it into a single line of text with \n replacing the line breaks in the file, until it ends with another quotation mark. I have declared message as so:
public static String message = ""; at the end.When I change this to StringBuffer however, I get a whole new slew of errors.
I didn't mean that you should just change the declaration and expect everything to work, but I didn't know enough about what you're doing to give more specific advice. I still don't think I have enough info, but I'll post some code to illustrate my advice. import java.io.*;
public class Test
{
private static String message = "";
public static void main(String... args)
{
try
{
BufferedReader reader = new BufferedReader(new FileReader("Test.dat"));
String line = reader.readLine();
if (line != null && line.startsWith("message=\""))
{
StringBuffer sb = new StringBuffer(line.substring(line.indexOf("\"") + 1));
sb.append("\n");
while ((line = reader.readLine()) != null)
{
if (line.endsWith("\""))
{
sb.append(line.substring(0, line.length() - 1));
break;
}
else
{
sb.append(line).append("\n");
}
}
message = sb.toString();
}
System.out.println(message);
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
}
My Test.dat file contains message="blah blah blah
blah blah blah
blah blah blah"
